In the more advanced design, the major striking stick is attached by a bearing to the handle, and rotates about the handle. That way, the mass of the arm and shoulder used in swinging transfers its momentum to the striking stick, providing faster speed to the striking stick. Also, the operator can spin the striking portion, applying repeated strikes in a fraction of a second.

They call it a smart stick because it makes you smart, alright.

My understanding was that there were two major advantages to jointed night sticks:

1. The "slapping" or "whipping" effect (tip of the stick travels much faster than would otherwise be achievable with a rigid stick) and

2. The wielder is protected from the shockwave of the impact (Newton's 3rd Law) and from the vibrations traveling back up the stick.

Maybe that's what you were saying (I had difficulty visualizing what kind of a device you were describing).
