The UltiClip Classic is a strong steel clip you can attach to the sheath of a fixed knife or holster to safely carry it in your pocket. The clip makes sure that you don't take the sheath from your pocket. At first opening the clip might be a little difficult. This, however, ensures that it is properly secured to your pocket. You could also attach the sheath to a backpack pocket, for instance.
The UltiClip Classic has one mounting hole. As a result you can still rotate the clip in relation to the sheath. The clip comes without screws.
