Unless you are doing some really thin grinds like on kitchen knives those steels are actually really good for you since they are air hardened in some sort of 02 free environment and don't have any decor. If I remember .0010 is ok with most heat treaters and a friend was able to do a couple of pieces for me that I forgot and went thinner and there is no warp and they just need a bit if cleanup. You might have a little bit of tough hand sanding but if you want a hand finish you are going to have to do that anyway.This is legit the first time I used this jig.. I just made it and went at itlol. I've also been working with my hands my whole life so there's that. Watching all the videos and such helped a lot... compared to that time I took a blacksmithing course. THAT didn't go so well.. :|
I want to use the cool stuff like 20cv and M390 to make some knives so a belt grinder will be pretty much needed then no? I know we can rent time on them at the local Forge, might be a better option.
