The skull idea reminds me that I saw on one of the truck shows where they went to a plating company and they chrome plated an actual skull.

How about a small pickaxe head like a t-shifter?

D-handle like a short shovel?

Saw this on google, but I think making one would be cooler. This one is just to pretty.

When wrestling a grizzly bear, you have to keep at it until the bear gets tired, not when you get tired.
