Katana

Katana (刀) is the word for "sword" in the Japanese language. It is also used specifically for a type of Japanese backsword or longsword (大刀 daitō) in use after the 1400s: a curved, single-edged sword traditionally used by the samurai. Pronounced [kah-tah-nah] in the kun'yomi (Japanese reading) of the kanji 刀, the word has been adopted as a loan word by the English language; as Japanese does not have separate plural and singular forms, both "katanas" and "katana" are considered acceptable plural forms in English.

Roronoa Zoro typically weilds 3 katana at once.
