I used saw blades to make the blades for these knives, fork and spear. These were Christmas gifts for my son, wife and myself. I used hard wood from a discarded wooden tray table for the handles.
We have a lot of old barbed wire around our property on the old fences. Most of the fence posts are falling down and the wire is available for us to use in a variety of ways. My wife suggested we start to get creative with it. This is the fist thing we tried.
