This is the handle of a Kozuka, used on Japanese swords. It comes with a wooden box. It appears to be made of copper. The handle has gold inlay, seemingly depicting shells. The wooden box has the characters "Kozuka Fukuro Kaizukushi" written on it. The thickness is approximately 0.5cm. Please consider all measurements as approximate, as they were taken by an amateur. There is damage to the part of the Kozuka where the small knife is inserted. Details are unknown, so please confirm and make your own judgment. Condition: Possible stains, age-related deterioration, and signs of use. Thank you for viewing. #Kozuka #Copper #Arms #Sword Fittings #Crafts #Japanese Sword
