The Tsuba of the Katana
kakata japan sword saber
Tsuba are the guards of Japanese swords (katanas, wakizashi, tantos). Their goal is to prevent the opponent's blade from slipping on the saber and cutting off the hand.

Tsubas are made from a wide variety of metals including iron, copper (red) and its derivatives such as yellow copper, bronze, shibuichi, shakudô, rogin but also gold and / or silver.

Each tsuba has a size (5 to 10 cm), a slice and a particular shape. It is however possible to identify ten different shapes: round (Marugata), "square" with rounded angles (Kaku gata, Yuko Ito gata), quadrilobate (Moko gata, Tate Ito gata), rectangular (Aori gata). .

The first tsubas date back to the 6th century. Much simpler in shape (in the shape of a drop of water) they were generally made of an alloy of copper or iron. Before that date some tsubas had to be imported. It is still possible today to find craftsmen specializing in the manufacture of tsubas.

It is possible to classify the tsubas according to their "style" allowing to identify the belonging to a school, a period and / or a particular factor. Some tsubas being signed it becomes "easy" to retrace the history or rather that of the postman.

There are several peculiarities of the tsuba, each one having a specific function:

The Nagako-Ana:

The Kozuka-Hitsu:
