larrin's...what about the grind...it looks like it is being heat treated withoutbeing ground at all?.....all the bevel work is done after heat treating?....any reasons for that imparticular.....ryan
Some makers choose to grind to a certain bevel thickness before heat treating because the grinding becomes more difficult after its heat treated. This is especially important with high alloy steels like S30V and 10V. It's also possible to overheat the blade after it has been tempered and ruin or modify the temper. However, heat treating is somewhat easier before grinding to help prevent warping and also it gives very flat surfaces if plate quenching.
My guess is this is either AEB-L or 19C27 damascus which is pretty easy to grind after heat treating. Overheating is not much of an issue if proper precautions are taken when grinding. It's mostly a personal preference, and here it appears that my father felt it would be easier to do it this way with Calista.
