The word "SHUN" means season in Japanese. The blade is made of 15 layers of blue Damascus steel. The Shun is the most basic style among Kanetsune field knives and ideal for backpacking, hunting and other outdoor activities. The knife also includes a Japanese traditional-style wooden scabbard sheath with leather belt loop and metal copper accents. Blue Steel: Called "Aogami" in Japan, is made by adding chromium and tungsten to white steel making it more durable with greater edge retention. These knives make a great collectible piece or an everyday work knife.
