Types of bokken

The following list is the basic styles of bokken made - the Japanese sword:
*daitō or tachi (katana-sized), long sword;
*shoto or kodachi or wakizashi bo, short sword, (wakizashi-sized);
*tanto bo (tantō-sized); and
*suburito can be made in daito and shoto sizes but are meant for solo training. They are much heavier and harder to use, developing greater muscles, increasing skills with 'normal' sized bokken.

Bokken can be made in any style of weapon required. The All Japan Kendo Federation specify the dimensions of bokken for use in kendo kata.
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.
