Abstract
An ice axe device comprising a handle having a gripping end and a working end and an impact member attached at the working end. The gripping end is configured about its longitudinal axis with a smaller, forward curvature and a larger, rearward curvature. The smaller, forward curvature is approximately defined by a radius slightly smaller than a corresponding radius of an arc formed at an inner surface of the user's fingers when wrapped about that portion of the gripping end. The larger, rearward curvature is approximately defined by a larger radius which is slightly smaller than a corresponding radius of an arc formed by a users palm and a proximate inside portion of an extending thumb when wrapped around the gripping end.
