Bonehead, my Normskull is a wood carving. I think all of his skull knobs are carved from wood. I think he uses different kinds. This one is about 4 years old. It's coated with epoxy I think that is tinted with some grey. I'm not sure how he end's up with that finish. Do you think you could make me an Indian with head dress? Actually as a gift for my dad. He has a 48 Poncho.
Here's a link with some info about Norm Grabowski. He carves other things too.
