BOKKEN (wooden sword)
History: The bokken was a popular samurai training sword because it was safer and less expensive than a "live" blade. When used in competition it could be fatal, and samurai would often keep a bokken nearby while they slept, so intruders could be captured without spilling blood within the house.
Traditional use: The bokken was primarily used to practice blocking and entering techniques.
Current use: The bokken is still used in place of the katana (sword) for training, competition, and demonstrations.
TANTO (knife)
History: The samurai wore the tanto either alone, or with the tachi (long sword).
Traditional use: The tanto was used as a thrusting weapon in ciose combat, although it couid also be thrown.
Current use: While tanto-jutsu (art of the dagger) is not widely practiced, the weapon can be used in kata demonstrations and competitions.
NUNCHAKU
History: Developed in the 17th century by Okinawans after the Japanese gained occupation of their land, the nunchaku (flail) was one of many harmless looking weapons implemented at the time. The two equal sections were originally held together by horsehair and could be used against armed or unarmed assailants.
Traditional use: The nunchaku was originally an agricultural tool used for threshing grain. As a weapon, it was used in conjunction with various stances and techniques. The sticks could be used for spearing or striking, and the chain could choke, block, or trap.
Current use:The nunchaku is a popular weapon for demonstrations. It is also used as a weapon of self-defense by karate stylists and some law enforcement agencies
