RIP PR-24

Currently, batons are banned in California, even for civilians. The law was overturned by (Saint) Roger Benitez in 2024 but is still on appeal by the Ninth.
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.
