OK then...If I understand correctly, the best,most controllable and easiest way to get a thoroughly softened spine would be to do a differential quench where just the edge is hardened, followed by 2 hours in the toaster oven at say...350 degrees...and then follow that up with the edge submerged in water and a torch applied to the spine? Does that sound correct...or am I beating a dead horse here? I don't want to do unnecessary work and I really don't even need a thoroughly softened spine....but I would like to know how to get there. Does thei discussion apply to basically all types of steel...or are we just talking about 1080,5160, and 52100.
