Fake Sword/Origin

Origin
A bokken (木剣, bok(u), "wood", and ken, "sword") (or commonly as bokutō 木刀 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.

The bokken is used as an inexpensive and relatively safe substitute for a real sword in several martial arts such as kendo, aikido and kenjutsu. Its simple wooden construction demands less care and maintenance than a katana. In addition, training with a bokken does not carry the same mortal risk associated with that of a sharp metal sword, both for the user and other practitioners near by. While its use has several advantages over use of a live edged weapon, it can still be deadly, and any training with a bokken should be done with due care. Injuries occurring from bokken are very similar to those caused by clubs and similar battering weapons and include compound fractures, ruptured organs, and other such blunt force injuries. In some ways, a bokken can be more dangerous as the injuries caused are often unseen and inexperienced practitioners may underestimate the risk of harm. It is not a sparring weapon, but is intended to be used in kata and to acclimate the student to the feel of a real sword. For sparring, a bamboo shinai is typically used instead for obvious safety reasons.

In 2003, the All Japan Kendo Federation (AJKF) introduced a set of basic exercises using a bokuto called Bokuto Ni Yoru Kendo Kihon-waza Keiko-ho. This form of practice is intended primarily for kendoka up to Nidan, but can be beneficial for all kendo students.

Suburito are bokken designed for use in suburi. 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.

Bokken are currently (as of 2011) issued to the Los Angeles Police Mounted Unit for use as batons.
