The material used for the confection of the Tenouchi determines its durability, as well as how much you can feel the Shinai in your hands.
Clarino/ Synthetic deerskin : Material with a look and properties close to deerskin.
Micro-punch Clarino/ Synthetic deerskin : Material with a look and properties close to deerskin, with small holes to improve breathability, which makes it less sturdy.
Ultrasuede: Higher quality synthetic leather. Thinner and with a improved feeling, it improves the precision of the movement and the confort inside the Kote.
Deerskin/ Shikagawa : The most resistant material used for Bogu. It allies a great sturdiness with great flexibility. It is, however, more difficult to dry than other material, and require more maintenance.
Chagawa : Normal Shikagawa which has been smocked to improve its resistance and durability. Well known for its unique smell.
Kongawa : Normal Shikagawa which has been smocked to improve its resistance and durability. It has been dye with Aizome. The smell is fainter that Chagawa.
Shirakawa : Bleached deerskin which has not been dyied. It is thiner than Chagawa and Kongawa which helps to feel more the shinai in its hand, but it is less resistant, thus it is not recommended for regular practice.
