hachiwara

In pre-industrial Japan, the , or "helmet breaker", was a type of blunt, knife-shaped weapon, resembling a jitte in many respects. This weapon was carried as a side-arm by Samurai, and was used to parry an opponent's sword or hook into an opponent's helmet.The blade of a hachiwara was a curved triangular rod with a hook on its backside. In combat one could parry and catch a blade with that hook, as with a jutte. Hachiwari were usually around 350mm long. Some larger versions are around 450mm long and resemble a tekkan.The mounting of a hachiwara is often designed to look like a tanto and some few haciwara are knives, rather than blunt metal cudgels.

Ein Hachiwari (jap. , dt. „Schüssel-/Schädelspalter“), fälschlich auch Hachiwara, war im mittelalterlichen Japan eine von den Samurai getragene seltene Beiwaffe, die zum Abfangen oder Einhaken genutzt werden konnte. Die Samurai trugen neben dem Langschwert Tachi standesgemäß ein Kurzschwert, eine Beiwaffe Kodachi. Es gibt überlieferte Hinweise, dass vereinzelt anstelle dieses „Beimessers“ auch Hachiwari geführt wurden.

L', noto anche come , era una sorta di stiletto a sezione triangolare e a lama smussata usato in Giappone nel periodo feudale.Lungo circa 30-35cm (anche se alcune versioni più lunghe raggiungevano i 45cm), era incurvato ed presentava un uncino sul dorso, vicino alla base dell'impugnatura. In certi casi la fattura dell'hachiwari era così simile a quella di un tanto da essere considerato un vero e proprio coltello, piuttosto che un randello a lama smussata.
