These are the factory kydex sheaths that are typically sold with a SURVIVE! GSO-5. They are designed to be versatile and come with a molle compatible belt clip. The sheath will also accept molle-loks, tek-loks and a variety of other mounting options. The sheaths come ready to attach on your belt for right handed users, or the belt clip can easily be moved to the other side of the sheath for lefties. With excellent retention these kydex sheaths are a reliable way to carry your SURVIVE! knife and the indented thumb press makes it easy to get to your knife with one hand.
