It looks like it could split a skull or open one up like a fish without any trouble at all.
A few years back after an accident I took to using a 'walking stick' made from a nice piece of hickory with a lovely burl on top for a grip.
It looked innocent enough but between the blunt end, the hard rounded burl, and a good stiff shaft I felt pretty well armed and confident I could handle almost anyone who was not armed with a firearm.

Hmmmm. I may have to be on the lookout for such an artifact. Might not be a bad thing to keep in the umbrella stand. In fact, we're going to a high-end artists' guild show on Sunday, where there will be some woodworkers who might have something like that on hand, or a least have materials for and be able to make, a nice one.
