Some Spyderco sheaths are equipped with a G-Clip. The clip has a leveraging thumb push-off point allowing you to safely position your hand and push/release the knife from the sheath. It affixes by way of a tension/spring clip in five carry positions: vertical, horizontal, inverted, cross draw or small-of-back (for shoulder or waist attachment). The G-Clip allows the knife to be carried securely and unobtrusively against the body or pack.
Carry options include: Inverted Cant, Forward Cant, Rear Cant, Vertical, Inverted, and Horizontal.
