I have a picture of the back of the sheath somewhere, nothing fancy though, just sewed a belt loop on the back.I made the sheath where the knife fits real snug, I don't think it would ever come out on it's own.
As far as the Cutco knife, a buddy of mine butchers his own meat and I bought the knife for him as a gift and had his name engraved on it, Wanted to make him a sheath for it and decided to make it where you could see his name on the knife.
