    As someone with an engineering background in regards to curved swords handling flex along the plane of the edge I can say that multiple effects of the geometry are assisting with resisting plastic deformation of the steel. First you noticed that the edge tends to be easier to align which helps to minimize the potential torque the steel receives. Second the curved shape minimizes the amount of blade in the target at any moment and maximizes pressure along the smallest or at least smaller arc of the edge. Last I'd point out many curved swords maintain more total metal from edge to spine from the center of percussion to the tip so having more steel total at the point of impact helps to absorb energy and resist bending both elastic and plastic deformation. This also pushes mass further forward and gives greater momentum for the same speed and force applied with the body. Many specialized thrust oriented swords become very narrow at the point or have a high degree of flexibility in temper so there is less metal to absorb stress and or bend elastically to avoid deformation and damage. The net results being a generally reduced ability to cut through resistive media and increased likelihood of blade damage with poor edge alignment. Lastly you referred to an arched bridge pointing out it's general ability to hold more weight than a straight surface... This isn't quite correct with an arched bridge the weight is being delivered at an angle through the material so it acts as though the material is thicker than it really is because the weight is supported through the arch shape to the ground. A closer similarity is seen in modern tank armor where angled plates are effectively thicker and the angle of the armor helps deflect impact rather than always absorbing the full force of enemy fire. Hope this helps and is of interest.

    I'm reading a book called "The Last Full Measure: How Soldiers Die in Battle" by Michael Stephenson, and just came across a couple of different viewpoints on this very issue from contemporary sources. The first was an argument in favour of straight swords, from a French cavalry specialist named Grandmaison in the mid-eighteenth century: "A single thrust into the body with the point will kill a man, which frequently cannot be achieved with twenty cuts with the edge." On the other hand, this was the opinion of a Hungarian cavalry officer who was writing during the same era: "I know that straight swords deal a more deadly blow, but they are not nearly as effective in combat. If you need convincing, I will explain the mechanism of the two kinds of weapon. When he is at a full gallop and a cavalryman attacks his enemy with the point, he will inevitably pierce him. But he must stop and break off his part in the action, so as to pull the sword out. During an equivalent amount of time a dragoon with a curved saber will have wounded three or four enemy, without having to stop his horse or stop fighting. The enemy will not be mortally wounded, but at least they will be disabled, which is what we ought to look for in battle."

    Puncture to be quickly lethal is limited to eye, heart, throat. Small protected moving targets. Anything else has delayed effects. A man with 30 seconds to live can still kill. Plus the vacuum of the body will suck the blade in. A massive cut is incapacitating with shock and blood loss. And will not stick. A cut returns naturally to guard on the follow through whereas a thrust leaves you open.

    It's interesting to note that curved swords are overwhelmingly (though not exclusively) used by light cavalry and cultures that emphasized light cavalry. Most of the advantages you talked about in the video are especially important for light cavalry. For instance, the curve providing a more natural cutting motion means that your blade is less likely to be stuck in your target while you do a ride by attack.

    Physicist: The curve changes the vibrational mode of the metal stick, so that less of the force is lost to blade 'waves' about the point of impact. I think this kind of explains a number of points made (the cutting contact point, the strength, and the other one). Its interesting. I've fenced sabre all my life and never given this any thought.

    After the constant bombardement of RSL advertisements, I finally succumbed, and installed the game. Let me tell you, it is one of the worst things I have ever played. Even compared to other Gacha games, like Danmachi, Girls Frontline, or Genshin Impact, the monetisation is offensively aggressive. You start the game, and immediately have to close several windows of their cash shop "offers". The gameplay is bland, the "story" is barely existant, and the "champions" are just dolls, without any characterisation, back stories, or personal sidestories to explore. The worst thing, however, is the upgrade system. You have to grind yourself through the bland levels to level up your characters. But to progress beyond a certain point, you have to upgrade their "star rating", which you can only do by sacrificing other characters of an equal star rating, and you have to sacrifice as many of them as the number of stars the character you want to upgrade has. At higher star ratings, you will end up having to sacrifice dozens of characters to upgrade a single one, and each of the sacrifices also have to be upgraded first, unless you buy the higher end summoning crystals. And then, once you have upgraded your character, its level gets reset to 1, so you have to grind up its level all over again. Luckily, I resisted the urge to spend any cash on it, and deleted the game and my account after a week.

    On the subject of curved swords structural strength. Not to say, that your point is wrong entirely, however, the architectural arch comparison is definitely flawed. The structural strength of the arch is stemming from the forces being evenly distributed and redirected into the supporting structure (foundations). This will not be the case in a sword, because the ends are not supported in the same way nor direction. Furthermore, while an arch is capable of supporting high distributed load, it's resistance to impact is less impressive. Curved swords still might or might not be stronger for different reasons (mass distribution, less taper, maybe angle of impact or whatnot; But also remember you own point about the forces being concentrated in a smaller area, which might in fact make it easier to damage the blade);

  • @Talishar

    You can instead just model it like a curved cantilever beam. In that case, the end that's gripped acts as the force concentration point. If we assume that the blade is perfectly made with no imperfections throughout the blade, then the greatest point of focus is where the grip meets the blade or the support. The curve is still very beneficial when you make some basic assumptions.

    Civil engineer here: About your point that curved swords are stronger due to arch effects - this almost certainly isn't correct. Arches are used a lot in concrete construction, as concrete is strong in compression but weak in tension. An arch bridge works by directing loads directly to the supports on both sides of the banks directly under compression and there is little to no tension in the system. The foundations of the arch also press sideways into the abutments, creating a form of negative moment that provides additional stability (similar to how the string on a bow pulls the two ends together - bow shafts actually work like an arch!), and if the foundation can’t take this horizontal load, the arch can collapse. Arches are generally effective with other materials, and are a very stable form. However an arch only works if it is supported on both sides, with a sword it is only supported at the grip, which prevents any benefits of the arched form. The only way a curved blade would have any advantage from arching action would be if the tip was also supported, and both ends were prevented from sliding apart from one another. One possible reason for curved swords being more stable would be because they are single edged blades (would also apply to straight single edge blades). With a single edged blade the spine of the blade tends to be (but is not always) thicker. The spine of the blade takes compression forces during impact, and tends to undergo an effect similar to lateral torsional buckling. A cross sections ability to resist against this is primarily due to it’s stiffness, and the thickness of a “plate” (blade) effects the stiffness to the power of 3, so a plate/blade that is twice as thick is 8 times stiffer (2^3 = 8). This is also why flexing of the blade to the side is significantly higher than in the direction of the blade, as the stiffness in this axis is for most blades several orders of magnitude higher, but they can flex in both directions.

    @ToddTR3 жыл бұрын

    To weigh in on the structural aspect of the curved blade: In the case of a basic cut, and setting aside the aspect of a curved blade's natural tendency to better align the edge on impact, a curved blade and a straight blade are approximately identical in strength. When looking at a typical arch, such as an arch bridge, for instance, we see a curved structure supported at both ends and a load over the center. That load is directed and distributed by the arch into both of the two supports in a manner that depends as exclusively as possible upon the compressive performance of the material from which the arch is made. Take away one support, as in the case of a sword held at one end, and we no longer have an arch. We are left with a system in which the curved shape has essentially lost its (structural) significance. There is no overall compression between the tip of a curved sword and the sword's hilt (while performing a standard cut with the center of the blade), and the material of the blade does not behave like the stones of an arch. The forces at play in a sword are the load upon the edge of the blade, the counteracting force at the hilt, and an additional torque supplied by the hand at the hilt in order to keep the system from rotating. (An arch needs to worry about little-to-no torque stresses as having supports on both sides of the load creates a symmetrical system that, thanks to the arch's nature, is all about compression.) With no force at the tip of the blade, and with torque therefore acting throughout the system, the blade experiences tension along the edge of the sword, and an equal amount of compression along the spine. These forces are the same regardless of whether the blade is curved or straight. It falls upon the dimensions, cross-section, and material properties of the blade to withstand these forces. TL;DR The parameters of this scenario are very different from those that allow an arch (bridge, roof, or what-have-you) to massively benefit from its curved shape. Therefore, two swords that are the same in every way other than curvature will have virtually identical blade strength when cutting. This does not, however, account for other differences between the dynamics of straight and curved swords, such as the natural angles of impact, edge alignment, etc., nor does it include cases outside of a squarely-aligned ideal-world cutting action.

    Structural engineer here, and I agree. You MIGHT get some effects due to inertia, if the accelaration is large enough, which will cause the curved blades to behave like arches, but I think this effect would be negligible. Otherwise, straight swords and curved swords behave like cantilevers when struck and will have the same strength if they have the same cross section and material strength.

    10:03 - you can also think; You're not removing the sword from the shealth. But rather, the sheath from the sword. i.e. Push the sheath forewards before drawing. Then, draw the sword by keeping the handle position fixed in front of you. And moving only the sheath backwards (exposing the sword). This reduces the distance you need to move the arm holding the sword (speeding up the draw, by clearing more of the sheath) ;)

    Mechanical engineer here! I haven't done the maths, but my intuition is that *for the same cross-section*, the curve of the blade won't make too much difference to its bending stiffness. The comparison to bridges is missing a key point - bridges are supported at both ends. Swords are usually only supported from one end. Additionally, arch bridges get their strength by redirecting the load into compressive forces in the structure. That's great for materials like stone or concrete that are strong in compression but weak in tension, but steel is more or less equally strong in tension and compression. It's certainly possible to build a steel arch, but it's equally possible to build a steel truss or suspension bridge. All of which is to say: I don't think that arch bridges are a good analogy for curved swords. Having said that, from the examples in the video, it looks like curved swords tend to be taller (blade to spine) than straight blades, which will make a huge difference. All else being equal, the bending stiffness of a blade in that direction of curve is proportional to the cube of the height!

    From personal experience, I can say that one of my favorite things to do with a curved sword when I was practicing was to mix into my normal cuts false edge cuts and curved thrusts with a flick of my wrist mid swing. The people I spared with (used to fighting against straight swords) often didn't even notice the switch until they felt the impact and looked to how my wrist was turned the opposite way they expected. The typical response to this was to try and fight at distance and keep me out of measure with a longer weapon or thrusts to not even give me the chance because of how hard they found to defend against it. Not an expert-level experience by any means, but hopefully a useful or at least interesting anecdote for some.

    One of the things I love about your videos is that I can tell you've actually used many of the blades and do a lot of things right without thinking about it: centering the weight, rotating the torso for power & speed, etc. I can also tell you don't have that same experience with curved blades. When drawing a curved blade, step forward with the sword-side foot like you are doing a lunge instead of drawing that shoulder back. Drawing backwards like you are winding up for a baseball swing robs you of defense and time. Likewise, begin your thrust with edge down and rotate mid-thrust, away from the parry. Rotating before the parry gives your opponent an easier time. You can practice this with two suspended vertical strings. Thrust around the front string into the back one.

    Before the Heian tachi, with a continuous curve through the tang, there was also the kenuki-gata tachi - which had a curved tang but straight or nearly straight blade - and the tang was offset at an angle which gave a further impression of a deeply curved blade. The ancestor of this sword, the warabite-to, had the same feature. These were short, single handed swords with a single edged blade which was usually completely straight, yet the grip was offset at an angle. I have always been curious as to how such swords would feel in the cut.

    I knew about edge alignment and focusing force, but I didn't know there were more advantages, thanks for the info. I have some things to share. About the edge alignment. There might be more to what you said. Not only can you feel the alignment, but it also wants to be aligned. Shadiversity showed that when you support it in both ends, it rolls to being in line. When Jairus of All made God of War swords, swords on the ends of chains and the user spins, he talked about some rocket science in order for the blades to fly straight. I don't know how good of a job I'll do of explaining, but I'll try. There's an axis of rotation, and you want mass behind the axis of rotation in order to make the center of drag behind the line, so the mass trails behind. If the profile is shaped in such a way that the center of drag is behind the axis of rotation, the sword will to a degree self correct human error in edge alignment and maintain edge alignment when something tries to make it turn. The farther away the center of drag is from the axis of rotation, the greater the effect. Regardless of the center of drag, curves can put mass farther away from the axis of rotation to make them "wider". Wider blades will cut better than narrower blades with the same mass, POB, edge geometry, thickness, etc. I don't know if whoever is currently reading this understands why, so in case they don't, I'll explain. Think of a right triangle. At a constant height, the wider the triangle the more accute the angle of the base and hypotenuse. Imagine there's a sword hitting a target and it wants to turn, if it has enough energy to rotate the end of the sword x millimeters, how many degrees will the sword rotate? The wider the sword, the less degrees of rotation, the more the edge alignment is maintained, the less energy goes in the wrong direction, the more energy is exerted where it should be, the better the cut. Also, the wider the blade, the harder it is for the edge alignment to be thrown off by the target. When Skallagrim was testing a really wide longsword, the prinepe, he said it was very forgiving when you messed up the edge alignment. I think that it's because normally when you mess up the edge alignment, it rolls further out of alignment and doesn't cut very deep, but because this sword was very wide, it didn't get very much out of alignment and even though it lost some force going in the needed direction, it still had enough because of the acute edge geometry. Even if the edge geometry isn't super acute, wider swords will still be harder to throw off and more forgiving. Curved swords aren't all the same. For example, the kopesh will be "wider" but won't be self correcting. A katana will be self correcting and, but not as much as a shamshir. When you say that the profile causes the force to be focused, I agree. My first thought is that simply by visualizing it like your demonstration with the rolled up paper it's true, but with what I know about science, I agree that tests should be done to confirm it. I think Skallagrim has done some tests on that, probably not enough to satisfy science, but it's some evidence. As far as comparing a curved sword to an arched bridge, I don't think so, but I'm not an expert. If the arch tries to bend from the weight, it has to move out in order to maintain the length or compress and get shorter. Because it's supported on both ends, the connection supports it from moving out to maintain length, and the compressional strength of the material helps to prevent it from getting shorter. I would think both happen a little as no material is perfect, but I don't think it would be noticable. With a curved sword, there's nothing on each end of the blade supporting it from moving out to maintain length, the energy from the swing isn't isn't being applied in the direction that supports against that.

    I think you've missed some characteristics of curved blades that I consider important. 1. Tip cut geometry, which aids in edge alignement. If you grab a curved sword by the handle and put its tip on the table, flat on, then just release the grip a little bit, then the sword will naturally turn the edge downward. So even if the cut isn't perfect, the inertia of the belly of the blade will help in correcting the alignment. 2. Aerodynamic effect, which aids in edge alignment. Swinging a broad curved sword at exactly 90 deg to the motion, that is trying to deliver the cut with the flat, is not easy, because the blade acts like a vane on an arrow or an airplane tail and tries to steer the edge forward. Curved swords are aerodynamically stable with the edge forward. Straight swords are not. The use of this effect can be seen on many period depiction of XIXth century hussars charging. They hold their swords up, but with the edge backwards. Iwanowski describes a series of cuts which start with the edge backwards. The blade turns in the hand mid-cut. I believe that only with a curved sword delivering such cuts makes any sense at all.

    Re: the structural integrity: If the curvature of the sword means it concentrates more force in a smaller area, wouldn't that also imply that that puts a curved sword under stronger stress by not spreading the force out over as large a portion of the blade? Not a physicist, mind you, just a layman's musing.

Not the same here. 2) I picture a curved sword as an axe in the first half, but second half is contacting BEHIND the center of gravity and therefore extremely self stabilizing at impact and follow through, reducing your chance of turning sideways and bending, no?

    Usually materials can take more compression stress than tensile stress. When a blade impacts, the back of the blade is under tensile stress. Curved blades aren't double-edged so often, so there's more material to take that stress in the back. We'd have to take into account the comparable lengths of straight and curved blades, too. If there's a same amount of material used for both, and even the same cross section, curved blade has shorter reach. Same impact would cause less stress, if material isn't so far away from the point of impact, like in curved blades.

    With all due respect, the answer to the question is more complicated than just "arches are generally very strong, therefore so are curved swords." An arch is a particular kind of structure including certain conditions that are entirely different from those a sword encounters. Regarding a simple cut, both a straight and a curved sword are very nearly identical, which I explore in a comment above. There may indeed be some cases in which a curved blade has an advantage over a straight blade in terms of strength, but likewise there are cases where a straight blade is stronger. I can think of some such cases regarding thrusts. I can elaborate, or even draw up some diagrams if you're interested! I love this stuff. EDIT: Regarding spine thickness, you're definitely right -- having a single edge gives you room to beef up the back of the blade while keeping the edge nice and fine, which is especially helpful for preventing the blade from breaking in the center when the tip's inertia puts tension on the spine.

    Advantages of a straight sword: 1. Greater penetration. 2. Better aim while thrusting, so you don't miss the right spot, where you intend to penetrate. 3. Looks cooler. 4. Scabbard can be made to look like a walking stick. 5. While slashing with the tip, the enemy gets less time to react. 6. Greater reach with same amount of steel. 7. A greater proportion of straight swords have pommels which can be unscrewed.

    I'm not sure your arch analogy is entirely valid, as only one side of the 'bridge' is supported - by the hand. The other end is going to attempt to rotate towards the impact point, so you will have additional compressive forces on the edge side of the blade and tensile forces on the back of the blade. Both forces are, at least, in line with the rest of the blade.

    Re: quickly drawing the blade - It's a bit strange that Japanese swords became not only straighter but also worn higher on the waist as they transitioned from tachi to katana. Given how important quickly drawing the sword is to Japanese martial philosophy, perhaps the relationship between curves and quickdraw deserves to be further elaborated on.

    No it is not at all strange. The edge was flipped uppwards and as such the sword were moved higher, its the same logic to why edges downwards is worn low. The logic behind a straighter blade is in how the curve is manufactured. It is not as much a straighter blade as a shorter blade. A shorter blade is quicker to draw. And compared to a tachi a katana is streamlined for quicker draws and in particular quick draw-cuts (hence the edge upwards, high worn and shorter blade). Much of the development of katanas was done to fit a more "civil" and "self defence" setting, often on foot, then on horseback on the battlefield (as the Tachi was). During history though different schools and swordsmiths have experimented with length, weight, broadness etc quite often so there is much a bigger variation in historic katanas then is usually thought of (especially in the west).

    @@sirseigan the video stipulates that a lower draw gives a better range of arm motion and an edge-down draw (favored by the most other curved sword examples in the video) allows a more direct cut. I'm sure there are compelling reasons the Japanese found the high, edge up draw more efficient...it just wasn't elaborated on in the video and I felt it would have been nice to explore the topic further. I'm afraid i'm going to have to disagree with you on the curve difference between tachi and katana. As pointed out in the video, typical historical examples even had the tang angled differerntly, making a more extreme deviation in the angle of the sword. The fit of the tang to the hilt is a design choice that exists outside the manufacturing process of the blade. I'm an aware of the degree of variation between katana . While I'm sure there are plenty katana that sported an equal, if not more extreme, curvature when compared to a typical tachi, it remains true that the katana are generally regarded as a straighter sword (as noted in matt's other videos). Indeed, the degree of variance between the size, shape and curvature of katana seem to indicate that Japanese smiths had a great degree of control over the end-result of the manufacturing process. If this is the case, then having the end result be generally straighter than tachi is most likely a deliberate design choice, not an accident of manufacture.

    @@temperededge I agree that it is a topic worth exploring in more depth! I was merely pointing out that the evolution of the Katana and how it was worn is not so strange if one look at the circumstances around it. I am not sure you are familiar with how to draw a katana and how it differs from how to draw a tachi. If you are please bear with me, I mean no dissrespect and I will get to the point eventually 😉 A tachi was generally mounted to the belt, hanged low with the edge down (as already stated). Due to the mount it is hard to draw it in any other manner then with the edge downward or prehaps at the side. If you want to do a draw-cut you are quite limited. But as Tachi was primarly used on horseback, on the battlefield, mostly as a side arm during ritual one on one fighting (after the bow and spear/naginata/bizento was discarded) ther were rarely a need for such quick draw-cuts. A katana on the other hand was developed and favorized during a time where the battlefield fighting had become much less ritualized and quick draws and draw-cuts was in much more need - and much more flexible draw-cuts at that. This was then later even more in need when much of the fighting evolved to be done in a much more "civil" manner (as in not on the battlefield) with ambush attacks, not uncommonly indoors in tight spaces and quite often with unamored opponents (at least often without helmets) etc etc. As such is was developed to be used more on foot the on horseback (even though it was used in both contexts ofc). These new circumstances of war and the need to not only draw quickly but to draw-cut quickly is what drove the development of the katana. The katana scabbard was held loose in the belt without any mount. This allow you to to be able to draw-cut in 180 degrees instead of just 90 with the Tachi (sure you could most likely do it in 180 degrees with a Tachi also but it is not at all as easy and quick as the Katana). This also is a key feature in the actual draw technique as you do not just draw the sword from the scabbard, you also draw the scabbard off the sword, which the mount of the Tachi prevents you from doing. This means only half of the draw is done with the swordarm. This also allows you to quickly draw and cut while both move backwards and forwards, or indeed stand still. You can also draw in a very tight position were you draw the sword uppwards rather then forwards (a bit like a Viking sword that sits high in a shoulderstrap rather then low at the belt). And when you draw-cut with the edge uppward you right away can cut at the head and neck (or the main swordhands wrist and/or thumb) and as such in much better position to deal a fatal blow with the first cut (which was the ideal). A perhaps innteresting sidenote is that a katana worn with a full armour (mostly used primarly on horseback) the katana is mounted in a similar, if not identical, way as the Tachi; hanging low with the edge downward. You are absolutly correct in that the swordsmith did indeed have control over the overall curvature, especially when creating the tang and fitting the hilt etc. However the curvature in Japanese swordblades (excluding the hilt) comes first at the process of tempering where the spine is covered in clay to keep it soft and that is whats creates the curve of the blade. Up until that very moment the the blade has been straight. As such one could say a Katana is basically a straight sword, that is bent *hrrmm* sorry I ment curved 😄 So while the overall curvature and its properties is a design choice the curvature on the blade it self, as a biproduct of the tempering, is much less controlled. Even though where the main curve should be can be controlled the control over the curvature radious is much less then if the blade was made curved right from the start. The curveature is, due to the process, also imtimtly interconnected to other properties of the blade (such as wich parts are hard and wich is soft etc) where perhaps the radious of the curve in it self might not have been the highest priority, but who knows 🙂 On a Tachi, mounted with the edge down an angled hilt, or the main curve of the blade close to the hilt (Koshizori) would aid in drawing and point alignment from horseback (both mentioned in the video). However I personally am not sure what benefits those features would give on a Katana with how it was used in mind for quick draw-cuts... It could even be a drawback with less reach in the draw-cut (it is only the top 5 cm that is "supposed" to be used on a katana so the reach is a crucial thing). Perhaps that is why many Tachi that was made into Katanas had their root (the part close to the hilt where some had their main curvature) reforged into the tang instead of just shorten the blad at the tip. But I have not tested a katana with a koshizori curveature and angled hilt myself so I can unfortunatly only speculate on the differences...

    It seems like the swords that have the line of the handle behind the point of impact would be better for draw cuts. Once the edge bites, you can apply slight pressure by turning your wrist, and (through lever mechanics) that pressure is magnified at the edge, causing it to "dig in" as you pull or push the blade.

    Mechanically speaking only if the shock is applied directly perpendicular to the edge at the point of contact all of it would be converted into bending. So even a pointy blade (non parallel blade edges) already transfer some portion of the impacting force towards the main axis of the blade and thus reducing bending. This is of course more likely with a curved blade because it is less likely to have a contact with the blade exactly at a 90 degree angle to the blades edge.

    So about the "structural curve", I'm not conviced. I'm a civil engineer, so I know my arches, and for it to work you have to have 2 contact points and a force. With a sword, you only have one contact point (your hand) and one force (the impact). This means the sword acts as a cantilever, where its shape isn't really important. What Matt describes is probalby caused by the generely broader blades of curved swords, which are advantagious for a cantilever.

    One question. When you hit a target with the middle part of a blade, the part of the blade furthest away from you, behind the point of impact, wants to travel on in the same direction. Now, with a straight blade this section is initially already in the same position as the one that impacts and then gets ahead of it, while with a curved blade, the section behind the point of impact is generally further away from the target than the one that impacts. Could that make curved blades more stable?

    But the force components of the impact would be diversed, compared to the straight (90 degree) impact of a straight sword. This would suggest that a curved sword would be "more resistant" to breaking, but how much this would actually appear in real life? I'd wager not that much, as you'd need a spot-on contact; however, I do think that a curved sword might be more forgiving in that sense (because of the curvature the contact is more likely not be 90 degrees) Hopefully you know what my tired brains are trying to say 😂

    @@tapioperala3010 You are completely wrong. Curvature does not matter, if mass and distance from point of impact are same, force is the same. What matters, is cross section. Straight sword typically would be double edged, with something like diamond cross section. Most of the mass would be in the middle and very little at the edges and edges experience largest compression/tension forces. Back side being very thin and hard edge under immense tension is prone to crack. Curved blades are single edged, with cross section more like a wedge, with most mas at the back of a blade, exactly where blade experience most tension. More material, and usually less hard too, is much more resistant to breaking.
