Yeah. That’s it. I didn’t think they have used those since the 50’s.
A friend of mine invented the Rapid Rotation Baton that fits in a holster on your back. Very good weapon.
The last one I saw was in the early 90’s, and the guy was near retirement at the time.
You can still buy them.

They even make a “Denver” model.
