I am looking into making my first knife and I have been looking at some knife making supply websites and have found a few blanks that I like. All of the ones I like have already been heat treated so I shouldn't have to have that done right? Another question, When you guys cut the scales to the shape of your handle what do you use to make the cut? I'm sure some other questions will come to mind but that's all I can think or for now. Thank you!
