Lin, your right, then I started making knives I made my own, then Kevin Evans gave me one and it helped 100% now with this one I think I can do even better because of the 2" surface for the file to ride on. I think this takes up to a 3" blade, but I'll never make one that big. Something to remember is always use a sharp file. I've tried using the dull ones, they just cost you more time.
David I hope this explans it for you, if not it's to file the back of the ricasso (shoulder) for the finger guard to set flat.
