Please tell me more. My Mark 1 with a leather handle came with a leather black sheath. There is a suspicion that they are from Ka-Bar Short. Has anyone come across a mention of a black leather scabbard for the Mark 1? At least in the company's catalog for 2020, I did not find them. But this catalog does not contain Mar 1 part serrated either, but we know that they were produced. Help me please
