It’s a shame more fabric enthusiastics don’t do this, we’d have an army of skilled blade sharpeners and weapon/fabric enthusiastics could join forces and reign supreme
I think everyone should learn how to sharpen a kitchen knife at least.
Dull knives are dangerous, and it really only takes an afternoon to get decent at sharpening a knife.
Unfortunately there’s a lot of lore about knife sharpening, like how you need really fine grit stones, or a whetstone being the best, when in reality you can get a shaving sharp edge from a 20 dollar diamond stone from a hardware store. Sure, a 4000 grit stone will get you a mirror finish and a more refined edge that will last slightly longer, but even an 80 grit stone when used properly, will get you a good edge that will last for months without any other sharpening.
