got inspired after seeing some fish decoys on line,basically they are lowered through a hole in the ice and when a predator comes along it gets harpooned.
I carved this one from a piece of Bison bone whilst on my holidays with little more than my leatherman tool,i used the blade and file to shape and to finish used fine emery cloth and then brasso.
