Thanks all for the kind words.
TX , it is made from an old file. I got a dozen from an auction that were ground flat. I believe Dave said it was w2 steel & that he hates working with it, something about drudgery comes to mind.
Mysticbow, it is 7&1/2"oal, the blade is 3&1/2"
ALW, I just slow ground the shape out of the file, & finished it from there. No heat treating yet, I am a super rookie. We drilled the pin holes with a carbide bit. It is very hard steel. I wanted a lanyard in the back, but I coud not get thru with a bigger drill.
It took a while to sharpen, but I have no hair left on my forearms.
