I'm sure you'll call me a weight weenie -- but seriously, how heavy is this? Gotta be 5-6 pounds, right? Even apart from carrying it (which would get to be a drag very quickly), it seems like it would be very slow to maneuver, in the odd chance that you actually did use it as a weapon.
I guess I just don't get it, except as an experiment in making something sort of fun.
Asa practical matter, wouldn't an oak staff of the same dimensions be a more effective tool? If you wanted to, you could still give it a weighted foot.
