I'd take the edge down to about 40 thou......
Keep in mind it may not be 1095.......and if it is, it will need a fast quenchant to properly harden......real fast oil or water/brine.
It's easier and cheaper to start with known steel, but you still can end up with a good knife from lots of salvaged materials, so.......have fun and do your best.......ask if you have anymore questions and the gang here will be glad to help all they can......they's good peeps :D
