Japanese Spear-Point Marking Knife sheath (cap)

Very simple sheath (cap) for the Japanese Spear-Point Marking Knife from Lee Valley (Item 60N0704). The plastic little poach that came with it was not really adequeate protection and just falls off. https://www.leevalley.com/en-ca/shop/tools/hand-tools/marking-and-measuring/marking-tools/110953-japanese-spear-point-marking-knife
