I have one with a brass horse hame on it I keep a cane around due to back issues that have caused nerve damage that effects my legs. It's a twisted shaft like the one in he vid, just has a brass horse hame attached to it. It would smash anything hit with it. Probably turn a skull into a beanbag. I'll try to snap a pic later.
*Edit to add*
Here's a pic of my two canes.
I figure if I"m going to have to use one of these dang sticks I want something that looks a little....different.
