Just went there.... that is a fencing tool for setting up a wire fence.. if it fits your bill, and turns out to be rugged why not buy it? i can't tell if it is a cheap quality by the picture, but I bet it will break a car window. I rather doubt you would be able to pry open a door... the handle is too short, and i think you would need a 4' long crow bar to pry open a door.<br><br>So that bring to mind the purpose you really have more in mind is breaking a car window the way I see it, and a self powered center punch will do that in a far smaller package. Just in case you don't know that tool it looks a lot like a a ball point pen. To break a window you cock the device and place it on the glass to be broken, and release the mechanism ... A very hard pin point releases with some authority and the glass falls apart....<br><br>In the way of hatchets and ax's uses are many, from a weapon to doing the intended job which is to chop wood.<br>You may use a tool as an oridinary ax for prying by placing the blade in a crack and then pulling sideways on the handle. Don't under estimate a good hickory handle either.... I do not care for fiberglass handles. They tend to degrade from UV rays, and splinter. Most are not replaced easily, as the are epoxied to the head. Unfortunatly some traing in needed to be safe with any ax or hatchet. These seem to be ignored generally, and I would hate to tell you how many folks had had to have such a device removed from the shin bones I have seen.... ( I do historical re-enactments) Mac
