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). This was a heavy wooden peg inserted in the stone; when removed, it could be used as 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.
Kata in the Taira Curriculum
The Taira line preserves two tonfa kata:
- Yaraguwa no Tonfa (屋良小のトンファー): The first form. Uses all three grips: honte-mochi (natural), gyakute-mochi (reverse) and tokushu-mochi (special). The tokushu-mochi grip, where the shaft is grasped rather than the handle, is particularly characteristic of Yaraguwa.
- Hamahiga no Tonfa (浜比尌のトンファー): The second form, associated with the Hamahiga island lineage also found in the sai kata corpus.
