Suburitō

A suburitō (素振り刀) is a type of bokken, a wooden practice sword originating in Japan and used in Japanese martial arts.

Suburi (素振り; literally, "basic or plain swing") means "practice swing"; a suburitō is therefore used to practice sword-swinging.

The weight of the suburitō is used for strengthening and conditioning in addition to development of spirit.

A suburitō is commonly around 115 cm (45 in) in length, with a mass of 1 kg (2.2 lb).

Legend has it that Miyamoto Musashi carved a bokken that resembled a suburitō out of a boat oar as he traveled to his famous duel with Sasaki Kojiro, whom he supposedly killed.
