I have ordered a Zensport nylon sheath for my recently purchased AM Leonard floor knife. I sharpened the ground knife just enough to use for picking greens, but not sharp enough to be dangerous. I gave the sheath 4 stars because although the hole is reinforced with extra nylon I'm not sure it will last as long as leather. The floor knife fits snugly and snugly and when I insert it face down it doesn't seem to put much stress on the entry point. The time will show.
