A knife with a leaf-shaped, two-edged steel blade with a bone handle secured by rivets. The tang goes right through to the end of the handle. The blade of the knife is an English-made trade item, hafted locally - it fits the knife sheath.

European knives and metal blades were valuable trade goods, exchanged with Native Americans engaged in the fur-trade for beaver pelts.

The knife forms part of a collection of ethnographic material made by Admiral Sir George Back (1796-1878).
