ABSTRACT:
A safety device comprising an ice spike having a mounting piece strapped to the forearm of the wearer with a spike support plate attached to the mounting piece by a hinge. An opener is biased to position the spike support plate in an open position and the spike support plate is held in a closed position using a hook and loop fastener. When the spike support plate is in the open position, a spike attached to the spike support plate is positioned by a spring or the equivalent such that its pointed end points outwardly from the spike support plate. The ice spike provides a person who has fallen through a hole in the ice with a device capable of gripping the slippery edges of the hole such that the person can extricate himself from the hole.
