Sword Length
A Japanese swords class depends on its length in units called shaku. One shaku is just under one foot.
The three main divisions of Japanese blade length are:
1 shaku or less for tanto,
1-2 shaku for shoto, and
2 shaku or more for daito.
A tanto is a small dagger.
Blades between one and two shaku are called shoto.
Japanese long swords are called daito. A daito is longer than two shaku measured in a straight line. However, there is no enforced maximum length for a daito. Blades such as the odachi and nodachi are among the longest. |
