Bokken

Various types of bokken

A bokken (木剣, bok(u), "wood", and ken, "sword") (or a bokutō 木刀) is a Japanese wooden sword used for training in kenjutsu. It is usually the size and shape of a katana, but is sometimes shaped like other swords, such as the wakizashi and tantō. Some ornamental bokken are decorated with mother-of-pearl work and elaborate carvings. Sometimes, it is spelled "boken" in English.

Bokken are traditionally composed of red oak or white oak, although any hardwood can be used. In comparison, practice swords made of flexible, soft wood such as bamboo are referred to as shinai.
