<p>The present invention features an ice screw for use in ice climbing, wherein the ice screw comprises: a hollow shaft having a plurality of screw threads formed thereon for securing the ice screw to a body of ice; a hanger coupled to the hollow shaft for receiving a carabiner and supporting a climber; and a flexing crank handle coupled to an aperture or eye formed within the hanger, wherein the flexing crank handle functions as a crank arm for screwing the ice screw into the body of ice, and wherein the flexing crank arm displaces or flexes from a resting, cranking position to a plurality of flexed positions in response to a load induced thereon. The flexing crank handle reduces the chance for cross-loading of an attached carabiner due to the existence of a crank handle without requiring any manual manipulation (e.g., folding) of the crank handle once the ice screw is inserted into the ice structure.</p> |
