n. A wooden katana, used as a training sword
Wikipedia
A bokken (, bok(u), "wood", and ken, "sword") (or a bokutō , as they are instead called in Japan) is a Japanese wooden sword used for training. 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.
Bokken should not be confused with shinai, practice swords made of flexible bamboo.
