I am a firefighter who owns a Res-Q-Rench. It is a fair tool that is primarily a collapsable spanner wrench,for use with firehose, at which it does an acceptabe job. It does NOT fit all sizes of gas meter shut off valves(personal experience on the fireground). Trama sheers or a good kinfe will cut any webbing. If you use the glass break point, wear leather gloves as the force required to break tempered glass will cause your hand to follow the tool through the opening you just made and be cut by glass particles(personal experience) Do NOT use it on plate glass, as it shatters in spear like shards that can cause severe lacerations. I prefer a spring loaded center punch for tempered glass and a fire ax for plate glass. If you break plate glass use the tool at the top of the glass with the handle above the head, otherwise the glass shards will slide down the handle and give you a nasty laceration(s) on the fingures and hand/arm.
The Biel Tool, aka Pry-Ax, is a good personal tool that some firefighters carry all the time. It is very versitle. I learned to use it in vehicle extrication training in the 80's. It is not a bad tool to have around.
Go for the Biel Tool and leave the Res-Q-Rench, unless you are a firefighter.
