When I started prospecting I allways dug with my great grandfathers adze.
Thought it was time to modify it inspired by the tiger tooth off an excavator bucket ?
Mate that is a beautiful piece of artistry and I reckon it would work really well. I remember hearing of a timbergetter that cut his leg off at the ankle with an adze, very sharp and used for trimming sleepers if I remember rightly.
