ABSTRACT:
A wearable, self-deploying fall arrest device to resist sliding movement of a climber on a climbing surface includes a pick blade pivotable between a retracted position and a deployed position. A tip of an out-turned tooth on the pick blade can be oriented downwardly and outwardly in the retracted position to engage and catch the climbing surface. An out-turned fin can be disposed on the opposite end of the pick blade above the pivot to urge the pick blade out of the retracted position upon pressing the fin against the climbing surface.
