I bought a knife already made from a file for a good price and am doctoring it up a little. The original file handle was used as a tang, which places the blade edge a little high and the top edge of the blade way too high. I re-ground the blade some as it was pretty much untapered from the back until about 3/4 of the depth of the blade. This made for a thick angled edge. Now it's more V shaped in cross section and is a better slicing knife now. Then I just ground the top of the blade near the handle for comfort. I really did not want to take the handle off and put a guard on it. It's just a common man's knife. The guy gave me a great piece of thick leather and I made a side-seam sheath. It's really sturdy and I managed to mold the leather to squeeze the blade pretty well. It was fun for my first leather sewing project in 20 years.
