So i have posted a few forums, and made a few more knifes from all the help i have been given, but im here yet again needing more. I have been using a coal burning forge for my projects, which unless i cover my knifes, leave them pitted, and so my next big project is going to be building another forge, which i have already found the design using the stickies. What i am now wondering is how you guys test to make sure your heat treating worked. I have seen the brass rod test, but there has to be a more accurate way to do it. I also was wondering how you guys made your grinding jigs, i know some of you do it by hand, but i have just been using a block of wood cut so it gives the knife edge a 30ish degree angle. I was wondering how you made yalls jig, how you secured the knife to them, and what angle yall cut your knives at


Thanks for the help,

Kev0
 
Forge thick and grind thin and you can eliminate the pitting. As far as testing heat treat, if it will skate a file before tempering and pass the brass rod and some cutting tests after tempering, you could have a good knife. If you have good temp control (kiln, etc) and follow the recipe, you should have a good knife. If you have a hardness tester, you can say, "I have a good knife at RC 60."
 
What exactly do you mean by skating a file? You just mean not having it dig in or chip?

Yes, it just means that the blade is harder than the file and the file will skate across the steel rather than cut it.
 
More help-
One is a knife.
Two or more are knives.
There are no "knifes."
