Types of Bokken

Bokken can be made to represent any style of weapon required such as nagamaki, no-dachi,yari, naginata, kama, etc. There are many different styles these include:

daitō or tachi (katana-sized), long sword shoto or kodachi or wakizashi bo, short sword, (wakizashi-sized)tantō bo (tantō-sized)suburito can be made in daitō and shoto sizes
 

Additionally, various koryu (traditional Japanese martial arts) have their own distinct styles of bokken which can vary slightly in length, tip shape, or in whether or not a tsuba (hilt guard) is added.

Suburito are bokken designed for use insuburi. Suburi, literally "bare swinging," are solo cutting exercises.

Suburito are thicker and heavier than normal bokken and users of suburito must therefore develop both strength and technique. Their weight makes them unsuitable for paired practice and kata. One famous user of the suburi-sized bokken is Miyamoto Musashi who used one in his duel against Sasaki Kojiro.
