Dillonbuck;
Good evening to you sir, I hope the day behaved for you all out east and you're all well.
Because I've no access to heat treating equipment, at present I've been cold grinding them, which of course isn't the fastest or likely the best way to do it.
It's hard on abrasives too for sure, but if one is careful to have a big bucket of cold water there and keep the steel from discoloring it seems to work okay.
I'll note folks have said they're too brittle, but when I got this batch of blades, I put one in a vice and attempted to break it, then tried with great enthusiasm with a 22oz hammer to break it and didn't, so I figured it's not super brittle.
The ones in the photo I did with a disc sander as I was experimenting with a specific blade profile, which I more or less achieved, but it's tough to keep clean lines that way so those I was less satisfied with.
Thanks for the question, hopefully that answer made sense and all the best to you folks as we head into the Christmas Season.
Dwayne
