I don't show the edge, but its fairly thick still. For something like this would you not grind at all pre heat-treat?
As per Ed's advice, I will go to at least 120 on the existing scratches before treating.
What is the best way to straiten during tempering? I have seen clamping to a file/other strait metal, but I have also heard some people say to "over-compensate" using shims.
Thanks for all the input!
