When I ordered my Regulator, I got the sheath with it. It's a good sheath. But I gave that knife to a Marine neighbor, along with the sheath. When some kind dogs sent me a new Regulator, it was without the sheath. Not to worry. I keep extra sheaths around, especilly the very versatile SYKCO Cordura 6" ones. Last year, Spec-Ops decided to discontinue their Navigator sheath. They were discounted by a local vendor so I got two in the discontinued Olive Drab, one short one and one long one. The sheath is similar to the Combat Master but it has a transluscent blue film over the pouch drain hole to let a flashlight shine through it. The gimmick never caught on, but the sheath is just fine. It's a bit snug, but my new Regulator fits the long one well. Just thought I'd share this option with you dogs. I think it looks good in that sheath.
