I have an older Entrek that I purchased directly. It is pretty nice and has a decent kydex sheath. I recently saw one of the production models. Although I liked the knife, the sheath is not sufficient. It looks like two thin pieces of kydex/concealex/? slapped together with a few fasteners. Pretty flimsy, and no pressure retention system on the sample I saw. If I bought the knife, I'd plan on replacing the sheath.
