can you grid a saw into the back of a knife? Answered
want a sawback knife, not willing to spend 70$ on one just yet. So with a file, a hacksaw, and some sharpening stones, could one easily make a "saw" or some very coarse serrations on the back of a knife suitable for bush craft and basic survival/trap/shelter construction? wouldn't need to cut down a tree, just make notches in branches for traps, and basic things like that.
