I got some stainless "mystery metal" from a friend of mine in the military. It only hardened a small amount from a light oil quench, so I made a couple of kitchen knives out of it. They outperform the rest of the kitchen, so I think I lucked out. I'll post some pics at some point. If your steel shows to be magnetic, I'd say try it, but don't invest too much work into it, you may be dissapointed. A spark test might give more info on it's composition, too.
As for what to grind it with... What do you have? Anything that will move metal is a good start. I started with hacksaws and hand files, then one of those old crank grinding wheels, then a 1/4hp grinding wheel, now a 3/4hp belt sander. They all worked, the only variables have been speed and control.
