This reminds me of something I heard somewhere - If you're ever just really lost in the wilderness, here's what you do. You take out your knife and start sharpening it. Really put some effort into it. You want to make it super razor sharp. It won't be long before somebody comes along to tell you that you're sharpening it wrong. Then, you can just ask that guy for directions.

Speaking from experience here, honing your blade with a dry blade and a dry rock will minimize rock wear over time, but the blade will still be ground down, albeit by quite minor amounts. A stone that's about the size and shape of a bar of soap is ideal, both so you can grip it and so it's forgiving in somewhat aligning itself with the blade's edge if you're a bit off in your approach.

As kids we used to use stones to sharpen the sickles and scythes. You need to have the right type of rock around but so far when you have rocks it usually has some useful rocks. Not as convenient as a bought wet stones, but still nice and easy. If you are lucky or dedicated you might find rocks to cover everything from coarse to finishing-touch fine. And for a strop.... you got a belt.

If the rock is flat and harder than your steel, yes. My grandfather taught me how many years ago. Gotta find the right rock.

Some of my favorite KZread content is making things authentically. Making boiled linseed oil would be perfect for this channel, or maybe the Shadlands?

Sharpening and honing stones originally are just somewhat flat and hard rocks from nature with a fine grain structure. (Something like a quartz granite, or perhaps jade.) And some of sharpening stones you may buy in a store are mined in a quarry, although there are synthetics and diamond plates as well these days. And if you can get three natural stones of the same type, you can use the Whitworth method to true them up and ensure flatness which makes them better for sharpening. (I suspect Whitworth took an art that was already known, as honing and touch-stones are older than him. He just used a scientific approach to ensure that it was optimal - and that's the approach that was named after him.)

I have been using rocks to sharpen my knives and axes when camping for decades, you just need to break the rock to get a flat edge, possibly rub the rock on a flat surface to get it even flatter or find one that's pretty flat to start with. . Once the knife is sharpened I usually just use any sort of left over fat from cooking to protect the blade.

Although I would use that as aftershave, it smells so good 😅. I believe in some ancient manuscripts they mentioned using Hogslard on blades, which I guess is the same thing.

Rooting for you guys! Thanks for all the content!

On the question of helping to rust proof a non-stainless steel blade another resource most medieval adventurers would have would be a salt pork or bacon ration. After the fat has melted down during cooking the resulting lard would give you a protective (albeit smelly) layer. Reference sharpening larger swords, it might be easier to keep the blade still and move the stone over the blade rather than the blade over the stone. This seems to work better for me when I'm working with a machete.

I was actually thinking about this few days ago. Interesting. I think a good follow-up video would be to discuss about other types of "ghetto"-maintenance on other gear. Like plate armor, chainmail, gambeson, leather, etc.

Find a rock 2 or 3x the size of your fist, use another rock to break it in half. Grind the faces of the broken rock together until they are smooth, for best results do it while holding the rock underwater. I grew up off the grid I've been making my own sharpening stones for decades

Love your chemistry on screen! Keep up the great work!

About the flammability of oils. Its not the bottle or the thin amounts on the sword that is an issue, but the cloth drenched in oil. In particular when using linseed oil which self ignite in room temperature. When using pieces of cloth (or paper tissue for some reason) with oils make sure to store them in a sealed container, like a jar for example.

Fun video and very informative!

Definitely a great basic intro to the concepts of sharpening, but for the viewers.. the is much more to it and like Tyranth said, trying this without REALLY knowing what you're doing, you'll probably just ruin the blade. If you want to get into sharpening, learn on flat stones, and you'll probably ruin a few blades on those and perhaps a couple whetstones. Once you've got the technique, then try a random rock.

Love the vid. Always cool to learn about the less flashy aspects of how adventuring would be brought to the real life. Also On my way! To Youtreon.

When out in the sticks, I've always used a palm sized river stone to sharpen any dull pocket knives I've had, and it works pretty well in a pinch as long as you know what you're doing. In fact I believe these river stones are the reason why we use the term "whetstone". Because it's wet.

IMPORTANT SAFETY TIP!!! Linseed oil can spontaneously combust at temps as low as 120 degrees. If you have a rag with linseed oil on it, and it is laying out in the hot sun, it can combust. This happened to us when we were treating some wood in the backyard in the summer.

The effort and detail that go into these videos far outshines similar channels.

One thing, that seemed to make the sharpening with the rock much more difficult was, that it wiggles around, when used of sharpening, which makes it much harder to hold the same edge angle. Would you reccomend using a large or even huge river boulder for sharpening? It seems using those on the spot without moving them would allow you to move around more, like with the flat stone without using your angle.

Adventurers would probably carry a proper whetstone. Whetstones have been made for millenia. Not synthetic whetstones of course, they'd just cut a piece from different kinds of suitable rocks. They were commercially made and sold by merchants. Not all pieces of rock were suitable. Back in medieval times, probably even ancient times, they would import rocks from other countries specifically to make whetstones with. It's rather unlikely you'd get a sword made from a blacksmith, and don't get a nice rock to sharpen it with. Even commoners would have whetstones to sharpen their kitchen knifes with. surely an adventurer would get one.

Firesword! That sounds like quite the video of things to test since it's used in so many movies for flashy things

Hello Shad, nice video. I am a big fan. I briefly went through your upload history and I have never seen you do a forged-in-fire reaction video. I think you would have interesting and well-thought-out inputs.

Pretty neat to be able to sharpen your blade with a rock if it's all you got handy. Could come in useful for a day out camping or hunting for sure. I thought Shad was going to attempt to "skip" an arrow across the water with that arrow bit at the end.

Great video! Honestly made me wonder why I didn’t have an on-the-go sharpening kit in my survival/bushcraft bag. After I watched, went out and put one together.

Another great vid, sharpening on river rocks works fine as you have constant water to do the job. I did/do it sometimes with my Opinel knives, very versatile and cheap but great in function! After sharpening always put the blade into ballistic oil.

This is the sort of content I subscribe for. My era is heading into the modern world, but things like grind stones would not necessarily be around depending on a person's profession. Sharpening blades were a mundane task, even in the modern world, but we don't consider how life/death important it could be. It would also be equally as dangerously forgetable for some professions in the past. Bear grease is another oil used in the time period. Yes, it does come from bears. Various other animal based oils would also be used and can be processed easily in a kitchen today. Be mindful of salted meats such as bacon. Linseed oil is great, but always be careful of storage of rags. They can self ignite. I've been experimenting with alternatives that won't make my renters insurance hate me. Awesome video.

I could see if adventures traveled in small parties often, 1 of them could carry a sharpening stone if they were a nomadic group, but if they are only out for a week or two, a quick fix with a stone would be fine because they plan on returning to a village and fixing everything when they arrive.

Fire Swords! For the sheer spectacle. I wonder about wax, like from a candle. Never used it on a blade but I had something go rusty that I thought was well oiled and wax seems to be doing well. I need more time to pass before I'm really convinced.

There are some rocks that are really good for sharpening uses, to be used as grindstones, we have a lot of them in Sweden (Scandinavia). So much that sometimes Vikings used grindstones as ballast when going on lon journeys. They could trade these rocks to get what they needed and then just fill the empty spot with a simple useless rock from that area on the way home ...

Shad should get some medieval style spectacles

One option for oil might be birch bark oil, made by heating birch bark in a tin or something like that where you can put it in a fire and keep air out.

My Kukri from Nepal comes with two smaller knives incorporated into the sheath. If I remember they are called the chakram and kurta? One is completely blunt like the edge is 5mm thick and is ridiculously hardened steel. They use it to sharpen the other blades by almost shaving and then burnishing the edge. one of the more unique ways I've heard of sharpening.

Minor note: “whetstone” doesn’t mean it needs to be wet. Whet means hone, sharpen, or stimulate (as in whet one’s appetite). Some whetstones are made to be used wet, some dry, and some work well either way.

Just a guess, but I think depending on the type of rock, you probably could.

I keep limestone around for my machetes and hatchet. Grades range from 10-20 grit, 120-500 grit, and 1 that is 1k+ grit. The lower grit levels are either for blade repairs or cleaning the higher grit stones and smoothing them out. They get better with age, and limestone is common in my area and is a soft enough stone it can be shaped and formed for blade sharpening quite quickly.

@Christopher Craig I've got several stones. Some actually from Japan. You put too much emphasis on the difference when in practice they all sharpen the edges. Hence why I keep the slurry per it, which is the Japanese method to polish the blade. Long-term puts a very nice patina on the blade itself. And yes, FEPA was based on the accuracy Arkansas stones have due to consistency of the quartz content. Either way, it doesn't matter what the standard one uses. It's how you use the stones that matter. I also have an antique barber stone that isn't based on either standard per its age. It doesn't list grit levels on either side, but it polishes nicely and makes a very polished razor edge, and the makers if the stone would be happy to know their claim on this stone lasting lifetime's did happen. Unfortunately, the pamphlet was water damaged as I was considering donating it to a museum at some point.

When I was in the Vallegrande provinence of Bolivia, I was shown how the locals would sharpen their machetes. They would find a random large rock with a flat surface, pour water on the rock, and do circular motions with their blade on the rock. I tried it a couple times and got some success, but I was told that most of those Bolivians could get the blade razor sharp using that method. It is indeed possible to sharpen a blade with a rock in the wilderness, but I agree with you that finding the right rock grit and flatness are important.

Yes with caveats. You have to have a uniform surface and a rock that is harder than the steel. But I have seen in survival training how to find naturally occurring rocks and what to do with them to get them useable. They aren't perfect, but def better than a dull blade

You can even use bottom of mugs, and windshield edges to sharpen pocket knives kinda neat stuff.

I used to have a pair of river rocks that were one oval stone that I split on the edge and lapped (though at the time I didn't know it was called that) for about fifteen minutes, sitting in the cool stream on a piping hot afternoon. I split the rock by holding it down on the ground rocks and tapping another rock on top of it. I finish hone with a carefully held 5 inch Allen wrench. T-handle wrenches work best. Two to four strokes for each side, not running down any side twice in a row, using medium pressure. If I know the blade will be stored or not regularly drawn I've gotten good results from using old (rancid? off peak?) olive oil and hard wax. I got along well with used candle wax from unscented candles, but mostly I used a block of hard uncolored beeswax, and an oily cloth. First rubbing with the cloth. Then running the wax down the edge and flats. Followed by buffing the lines of wax. When I'm putting away a blade for storage I rub the wax in more deeply at the end. Otherwise a final slick coat of oil rubbed down the metal works. Either way, the blade has a coating that keeps more moisture away. I'm in the summer humidity of Indiana, so that's important.

If you're got the time you can make a more whetstone-like rock by grinding 3 rocks against each other, gradually flattening them. Why 3? Because then they will tend to being perfectly flat, with just 2 rocks one can end up concave and vice versa. Using three rocks and cycling which grind against which is how they used to (maybe still do??) surface plates for low-tolerance machining

Sandstone is pretty much a sharpening stone as is, and comes in various levels of grit, same as river stones. You could probably even use natural clay to make a type of pottery brick that could act as a sharpening stone. This is probably the most useful because you can customize the grit based on the clay you use. You could even make a fine stone by using river silt, you just powder the brick with it like you would flour on bread before you fire it.

My favorite thing to use, other than sharpeners with ceramic rods, is the bottom of a coffee mug. The bottoms are typically unglazed, large in surface area, and in a pinch even a broken mug can be used.

There's an untold number of jigs to help with keeping the blade at the right angle. You can even 3d print a block with the correct angle and use that. Sharpening in this day and age is so much easier than it ever was.
