Abstract

A tool comprises serrations that are in the shape of an arched chisel grind and consist of individual scalloped-shaped serrations of varying pitch and gullet sizes, the tool being secured in a heat resistant sheath by an internal spring release and catch. The tool is engaged to and disengaged from the sheath without mechanical manipulation and together allow the tool to be presented in a ready position in order to apply the serrations of the tool to self-extricate oneself from entanglement emergencies.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 62 / 252,601, filed November 9, 2015, the entire contents of which are incorporated herein by reference. Background technique [0003] Numerous case studies have documented firefighters becoming trapped or entangled in wires or cables, for example when ceilings collapse.
