They have a long Cordura and a short one (6" & 10"). Or at least they used to. The 6" would fit up to a 7" blade. They are on the order page. The 10" fits the Dogfather, BWM, and several other long blade knives. I ordered the 10" sheath with my 911. We will see if they are still available. The 6" was originally for the S6, but it fit a lot of 6" to 7" blade knives. THe one for the Regulator was a special one made for that knife. They also made a kydex sheath especially for the S6.
