Genuine cowhide, dark gray close to black. This is a deba knife case made from about 2mm thick, hard-type leather. The edges are laced with black leather cord for a stylish and simple look. The size is for a typical household deba knife with a blade length of 19 cm and a blade width at the base of 6 cm. Smaller deba knives will fit. You probably don't use it often, but how about carrying it around or safely storing it in a drawer? It's a very sturdy case. Please understand that this is a handmade item. *The knife is for display purposes only.
