This is probably a rehash of others, but just how much metal should be left prior to the heat? I would imagine that you wouldn't want to take it down to a razor edge because of warping issues. Any info would be greatly appreciated. Thanks.
 
You would get more answers in the maker forum, but I prefer to leave about 1.2 - 1.5mm on the edge before heat treating, depending on the type of steel. With some of the tool steels like O1 and D2 I found that warping is less than with some of the stainless steels.
 
Thanks for the reply. I'll try and posting this in the maker forum also. I'm trying to get as much as I can nailed down to try and prevent some mistakes.
