Friend gave me a knife, made by Ontario. It's a kabar style knife, that he found in the woods while hunting. The leather handle has been chewed on by pack rats and is pretty much shot. The rest of the blade is in good shape. I want to replace the leather, maintaining the classic look. The leather part is not likely that hard, just stacking leather washers. The part I need to sort out is, how to get the butt cap pin out. Hammered on it for a bit, with no results. Should I resort to a drill?
