180mm knife shaped nata, a Japanese style hatchet used for splitting bamboo or wood, this one is for splitting bamboo but can have lots of other outdoor uses.

Hand forged knives from the Tosa area of Shikoku Island, Japan's least populated island with a long history of smithing. Shikoku's thick forests, agriculture and fisheries have led to a local style of smithing that is characterized by rustic free forged knives and tools. Many Tosa knives are double bevel ryoba style; forged and ground symmetrically and are suitable for both right and left hand users.

This is a reactive carbon steel. It should be mentioned that extra care is required, as the knife is not stainless and should be dried immediately after use. It will develop a dark patina with usage, but any orange rust should be removed with a light abrasive.
