I love Jeff's leather sheaths but for the CG Mutt it seems to suit kydex better.
The spec ops sheaths are the nicest nylon ones. I wish they would make them bigger.

Jeff madde me a Yard keeper Kydex sheath that had mounting points for a belt loop or dmall tekloc on both the top and bottom. You could even attach 2 small teklocs and attach it anywhere. It made a tremandously versitly way to stash a knife anywhere like on your seatbelt or to the remote caddy on the side of your Lazyboy.
