To anneal or not to anneal
I am new to knife making. I just picked up an antique cross cut saw with the idea that I would make a few knives from the blade. Based on what I’ve read l, I am working with the assumption that this is likely a high carbon steel. Does the steel typical of these types of old sol blades need to be annealed before beveling the knife and drilling holes for the scales?

I would say it depends on the exact steel but I would think a 3 step normalization would work....I haven't worked with carbon steel in a while but if I remember the general temps right it would include....heat till about 1600 deg. let cool (not to room temp just let the color fade and maybe 1 more minute) then heat to 1550 again let cool then heat again to 1500 deg and let cool completely I would think that would be enough to be able to drill and do bevels without a problem...it also may depend on how you are doing the bevels for example I can do bevels after its hardened on my grinder if your doing it by hand with files that wont work...there are a lot of variables AND this assumes that the steel blade is a good steel to harden...even when I used to use carbon steel I always used KNOW steels like 1084, 1095 stuff like that but again these days I used stainless so if my temps are off on the normalization somebody will chime in.
