Bone knife with no tools whatoever

 I was on a stroll the other day and found a roe deer bone in the underbrush, so I wanted to try out some survival toolmaking techniques. Two sandstones and a bone were all that was at hand. I set the bone diagonally on edge on an "anvil" stone and split it with two whacks. The split smaller part I saved to make an awl later.

 This is what the bone looked like after the whacking. I then ground it on the stone.

 Dug for some fir root to make for a handle wrapping, did a quick wrapping et voilá, the finished knife, which took about half an hour to make. It actually cuts soft wood quite well, even if it´s not comparable to a steel or bronze or stone blade. I will use it as an awl and a bodkin for basketmaking.

 The knife and the awl.

I actually learned a lot in the process and hope to practice more skills like that in the future.
