Up for sale is an antique early 1900s pocket knife with a Zenith Marshall Wells leather sheath! The knife folds out and has a 2” long metal blade marked Czechoslovakia. The outside of the blade has a celluloid tortoise shell, there is also an ear/snuff scoop that folds out from the opposite side of the knife. Purchased at a local Twin Falls Idaho estate sale. I am unsure whether the folding knife and sheath go together? That is how it was sold to me.
