I'm new to this, working on 4 knives made of 440c stainless. I was wanting to do some filework on a couple of the knives on the handles. These knives will have to be sent out to be heat treated. Is it ok to do file work before heat treating? I've already done some file work on 1 knife, then started wondering if it could get damaged in some way during heat treating.
