Abstract: A friction barrier adapted to position between a support surface and a skin surface, wherein said friction barrier comprises a generally flat sheet material generally conformable by placement between said support surface and said skin surface, or a pre-formed material placed between said support surface and said skin surface, wherein said friction barrier has first side adapted to face said skin surface, the first side having a static coefficient of friction which reduces one or more of the mechanical factors contributing to blister development when the skin rubs against a support surface, including friction, pressure, shear, or moisture

Abstract: A containment system, and methods of making and using such a containment system, whereby the containment system includes a container having a container sidewall disposed between opposing container first and second ends; a cavity disposed in the container sidewall; a cover concentrically disposed about the container sidewall; and an aperture element disposed in the cover, the aperture element defining an aperture element opening communicating between cover inner and outer surfaces. The cover is rotatable about the container sidewall between first and second positions. In the first position, the aperture element opening aligns with the cavity, thereby allowing access to the cavity. In the second position, a portion of the cover overlays the cavity to enclose the cavity.

Abstract: Generally, a spike including a rotary position selector which allows selectable incremental fixed angular positioning of the spike, the spike adaptable to couple to a tool. Specifically, an ice axe having a rotatable spike which allows selectable fixed angular positioning of the spike in relation to the shaft of the ice axe.
