Tonfa — トンファー
The tonfa (トンファー, also written 答禍 or 当破) is a hardwood weapon with a perpendicular handle set approximately one third of the way along a wooden shaft. Practiced in pairs, it is primarily a close-range striking weapon with a distinctive spinning motion.

Origin Theory
The most widely cited origin theory is that the tonfa derives from the handle of a traditional millstone (tobira or tofa) — a heavy wooden peg inserted in the stone that, when removed, would be a natural hand-weapon. Whether this is historically accurate or a post-war folk etymology is debated.
Technique
The central technique of tonfa is the spin-and-strike: the weapon pivots forward around the handle grip to deliver a forearm-length strike, then retracts. The back end of the shaft protects the forearm while blocking. At close range the grip can shift to use the handle as a short thrusting club.
The modern police PR-24 baton is directly derived from the tonfa design, which accounts for part of the weapon's wider contemporary familiarity.
