These are some quick shots in the afternoon light of a little French style drawknife I made back in about 1970. It has seen a lot of use,as you can tell.
The actual cutting edge is only 4".The whole length of the blade is 6 1/4".The handles are Turkish boxwood. The ferrules are just 3/8" dia. model brass tubing.
I made this before I had any metal working equipment. The blade was sawn out of 1/2" X 3/32" 01 or W1 tool steel.I can't recall which. The arches were bent into the arms of the blade while it was still soft.. The bevel was filed on,then it was hardened with a propane torch. The soft tangs come out of the fat ends of the handles,and are bent over. Some of the blue temper remains on the arms. I advise drawing something this small blue,so it doesn't snap.
Anyone could make a similar tool without fancy equipment,just as I did this one. I used it a lot on violin necks.
