Bunko Bocho Sheath or Case Available?

[David45]

I love my Spyderco/Murray Carter Bunko Bocho but the very thin plastic cover it came with is very hard to use without cutting the plastic when inserting the knife. I’m pretty sure it is only meant to protect the blade during shipping.
Does anyone know of a good way to protect the blade when not in use? A good sheath or case?
(The Mrs. won’t let me put up a magnetic strip which would have been my solution)
