Ultra Broad Blade Katana for Row Cut Tameshigiri Review and Test Cutting, DMC Yamato by Ryan Sword

Спорт

This is the review of a custom specialty katana for tatami row tameshigiri challenges. Starting at a whopping 50.1mm motohaba as the width at the base, the blade is 60-80% wider than the average katana. Historically some of the rare specimens of these wide-bladed katana existed. Today shinsakuto like this are made in Japan for tameshigiri demonstrations at festivals and All-Japan Iaido Batto-do cutting competitions hosted at the Meiji Jingu Shrine annually. This particularly example designed by Brother Nathaniel and custom made by Ryan Sword has a spine tapered back from the shinogi-ji in thickness to reduce the weight, so while the thickness and distal taper at the shinogi-ji is typical for a katana from 7.2mm as motokasane down to 5.1mm as sakikasane, the mune tapers from 6mm to 3mm on its own. The sword has a 28.6" blade (27.2" nagasa) comes in at 1496 grams (3 lbs 4.76 oz)--quite hefty for its size, but with a point of balance of 6.25", it does a lot of the work for the user in tameshigiri challenges on a huge mass of tatami mats, such as a row of 7 mats. The ultra wide blade not only introduces extra mass, but drastically reduces the edge angle on the top portion of the blade to 10-12 degrees, which makes friction almost non-existent when the blade passes through targets.
I did some test cutting on a ballistic gelatin human thigh analog with a wooden dowel in the center--thicker than triple tatami mat roll, but denser and more resistant. The sword sailed through that without me even feeling the impact. Although being a heavy sword, it's still maneuverable so you can redirect the blade to attempt some double-cuts or even triple-cuts, but I showed how much slower it is comparing to a katana of average size and weight.
It is differentially hardened with a wide and bold hamon that has the edge tempered to 60 HRC, and the spine at higher 40 HRC. This is a fearsome specialty cutter tailor-made for cutting massive chunk of soft mass. John of RVA-Katana already contacted me to take the design of Brother Nathaniel for a model of specialty cutting sword made by Cloudhammer Steelworks, probably with S5 shock steel or SX105V Japanese tool steel. Stay tuned!

    Awesome overview Kane. This is a wicked sword, and you did a great job covering all of the intricacies of how it operates. It certainly cuts a mean profile in addition to being a fearsome cutter. Also a great PSA about the shampoo bottles: everyone should be aware of exactly how durable some types of plastic can be, and when we do our backyard targets, they can certainly cause risk to more thin/brittle edges. Great cutting and great contextual overview!

    Thank you so much! Indeed, I regret to a certain degree of using it on inappropriate test cutting medium. I examined the shampoo bottle dispenser later and found the plastic to be very thick (much more so than plastic piping, as there's only tiny space in the middle for the shampoo to go through, but the whole chunk of plastic is THICC). Good news is that the sword still cut it through like butter, but for sure differentially hardened blade with such a small edge angle isn't the kind of sword you want to use on that.

    Thanks for the comment, and glad that I can provide some entertainment with my videos. This design is now being turned into a regular model to be produced but per my recommendation will be made with mono-tempered Japanese super-steel, instead of the differentially hardened steel to be more durable, and has the tsuka increased by 3-5 cm in length, along with the nakago inside, to provide better counter-balance and more leverage for the user.

    Indeed. John asked me about the preferred cross section and I voted for this setup with shinogi-zukuri either the spine tapered back in thickness from the shinogi-ji, as it reduces some weight but still keep the edge angle from being too small. Still at the cutting portion it’s at 10 degrees, which is quite crazy. Being made in hira zukuri will make the edge angle even smaller. A risky gamble for sure.

    Nice! Fingers crossed that RVA will make this piece a production model. It's close to my "grail" katana, which would be a wide, yet thin hira zukuri style blade, but with distal taper and some niku. This way it could be light and fast, but still a devastating cutter. I can dream! ;-)

    I have a custom kanmuri-otoshi zukuri odachi blade mounted with 16th century European hilt furniture that has a similar blade width to the sword in this video. It was a proof of concept piece, and is right at the limit of what a functional sword can be. I just need to get some Berserker Armor now. Edit: I also have a custom shobu zukuri katana with a blade proportion similar to a niuweidao, and that blade swells to a little over 2 inches near the optimal cutting section. Both of these swords are great cutters.

It's big enough to make my Albion Archduke look dainty in comparison.

    ​@FortuneFavoursTheBold I spent some time trying to calculate the non-linear, but very significant, distal taper the blade would need to make it wieldable, but actually capable of surviving cutting a charging horse's legs out from under it (it's original purpose). Once completed, I deemed it capable of being able to actually go up against the concept of mythical monsters. Even at my six and a half foot stature (and broadly built), its mass pushes my ligaments and tendons to a limit that I'm not sure is reasonably surpassable. I can muscle my Archduke into moving like a longsword, but trying that with this monster sword would end up with a visit to an orthopedist for me. It forces me to use circuitous montante/zweihander techniques to prevent injury.

    This is the detailed sword page about Akashi Kuniyuki www.touken-world.jp/search-noted-sword/kokuho-meito/54135/ 13th century Japanese swords have far more interesting geometries than the most common reproductions of Edo period run of the mill katana. These tachi have non-linear curvature on the blade-more curved at The tang and the lower 1/3 of the blade than the upper 2/3 of the blade. It’s just something modern makers rare care to replicate. Akashi Kuniyuki also has a relatively slender blade with more distal taper, which is seen on earlier tachi often-because they have longer blades and are meant for war rather than the wall. There is also the double bo-hi (the upper one is shorter) and the reinforced kissaki, and the engraving on the base of tje blade. There are just tons of details here and I’m not sure Shadow Dancer is the one to go for, even though they make good swords in general. They are not known for making historical replicas and stepping outside their comfort zone. I think Cloudhammer is a worthy contender for the project given how willing they are to take on custom projects with interesting features.
