I carved the main design out of foam, made the teeth out of steel, and spray metallized the whole thing with zinc. The foam did not appreciate being melted so violently, which is why there are supremely lumpy areas.
Adding a pipe onto an axe or sledgehammer does two great things- adds a little more weight, and helps to extend the life of the handle. Missing and hitting the axe near the head puts a ton of stress on the handle, this protects it.
I also built up the bottom edge, which had worn away, with TIG welds, and then ground it back into shape.

Nothing like some cardboard, paper, sharpies, and a tape measure when it comes to designing new products!
I’m big on CAD- Cardboard aided design.
I don’t mind using computers or drafting programs, but this way is more fun, more tactile, and way more immediate.
The makers of Gon Kirin(literally, light dragon) wanted a sign to show off their ArtPrize voting number. I stepped up and produced this. It is entirely done by hand, using a soapstone line and an oxyfuel torch.
If you look carefully at the chest of the dragon, you can also see the gear ball logo that I made.
