I'm supposed to know these things, but obviously I don't have it down yet.   My current 8" chef knife started warping in my final set of normalizations?!? Any insights welcome (even those I've heard or read a dozen times).   Blade history: Billet of 1095/15N20 I forged - several hundred layers (theoretically 700+ but I know I burned off some and ground off some layers between cutting & stacking for each round).   Forged pretty much to shape & thickness - bevel & distal taper.
