@@behooman7749 You can make your own for cheap. That's not to denigrate the people in the video though, as I'm sure their whetstones are high quality. Now, normally we're looking for speed-rate of abrasion-and a fine finish on the edge from our sharpening solution. But you don't really need both if you do microbevels when sharpening. Modern abrasives are hard to beat for speed, but it's fairly easy to select natural stones that give an edge good enough for cooking or a wood chisel, and with a microbevel it doesn't really matter if your stone is slow. Of course, you'll need more skill/luck to find a really good razor hone, though I'm not sure how rare that actually is either and it depends on your local geology too. When looking at natural stones, look for one with a uniform texture (grain size at most the size of sand). If you clean it and rub it a bit on the flat side of a knife (hardened steel) it should leave a noticeable mark (you want a rock containing hard-enough minerals to abrade your steel). Small stones be flattened quickly with coarse grit diamond sharpening plates, which can be had for $10 or less on e.g. AliExpress. You want a quite coarse grit, like 120 or 80. You can smoothen the flattened face, if you wish, just by rubbing the stone on flat concrete or another flattened stone.
@@meandyou537 NP, I wrote all thinking nobody would read it hah. I should add a few more things: -grind your stone wet to avoid dust -start your grinding on a flat-ish face to save a ton of time -For tougher stones like quartzite, plan on it being pretty annoying to grind more than like a 2"x2"/2.5 cmx2.5 cm area flat. With softer ones you can get a much bigger area. A stone isn't better or worse necessarily just because it's easier or harder to grind. -To sharpen a knife on a small stone, it's easiest to do a jabbing motion with the knife (so the stone is travelling parallel to the edge), or mount the stone on a small stick and run it over the knife. Feel free to ask more. Making your own whetstone is an interesting thing without too much information on it online. I'm still learning too.
A great look into the past, thank you.
Este video es muy bonito amigo 😊👍
Excellent ✴️
砥石の成り立ち！
Chert? I would have thought this mineral would be friable enough to break apart if used as an abrasive. Apparently not!
And how much would such stone cost to the customer?
Most likely a Few hundred to couple thousand dollars
@@TatsukiHashida 2000 dollars? Damn!!

@@winrawrisyou Thanks for the for-beginner lesson! Much appreciated :)
