The drill has a spindle tip fitted into it. It wears out and a new one is fitted. Mine's the same.
It allows different tips to be fitted; a rodent tooth, or a bit of flint to bore a straight sided hole through wood or a shell for instance. A very good tool
Landward is segments; I'm just really pleased to see bushcraft as one of them
and more pleased that it's someone who really does know his stuff that's doing it
Interested to see what he does next week too
cheers,
Toddy
