As a rule, the handle is designed as shown on our Diagram to explain the terms is the case. So a corpus with Same, Menuki, Tsuka Ito, etc. However, there are other designs that differ from this. We would therefore like to present a few other tsuka variants here.
Aikuchi

Aikuchi is the name for a complete mounting style that is more commonly used for knives (tanto). The main feature is that this mounting has no guard. The handle of this type of mount usually has no grip tape and, like the scabbard, is made of lacquered wood.
Same

The entire sword handle is covered with seed instead of the usual ray skin inlays.
Sendan
Rattan is attached to the body of the sword handle, resulting in a ring-like surface structure
Shirasaya

The Shirasaya mount is mainly used for storing swords. The handle of this mount is made of unlacquered wood without any other additional elements.
