Developed in the 12th Century (and used up to the 14th Century), The Kiritsuke was a Lamellar-style component. Often referred to as “The Turtle Shell” it was constructed of heavy plates of bamboo wood. As many as 40 shaved pieces (or plates), were heat hardened and treated with animal rendering fats. The drying process could take many months to create the necessary strength required. Designed as dual components (front and back), The Kiritsuke provided maximum protection against the many different blades seen in combat. Tied into place with silk cords (or ropes), it was used by Ashigaru soldiers and Archers.
