Bests & Worsts Reviews from Amazon

A window breaker is not a device to take trivially. A device that looks like it works is not good enough. Many pointed steel "window breakers" don't work because the steel is not hard enough. Even with the steel point! If you want a usable steel tipped window breaker, it MUST have hardened steel. The company will advertise this. Better yet, the window breaker can be certified by a governing body such as TUV that will confirm that the product does work. If the steel is not hardened and has no certification, don't buy it, plain and simple. Buy carbide if not certified. Another option would be to use a quality center punch because it is hardened steel and pointed. Even spark plug ceramic works as it is super hard. Whether the "reviewed" product is hardened and works well, I don't know. However, I suspect not. My one star review is intended to inform that there is a lot of junk out there. Decide for yourself what you want to buy, but you will not likely know if this works until you absolutely need it to work. I don't think it is worth the risk. BTW...Lifehammers are hardened steel and TUV certified. ResQme is carbide. Many knives are made with carbide tips for this window breaking purpose (I have a Kershaw Responder). They all work great because they have carbide tips. The Choate breaker noted in one of the videos is hardened steel, but even this has trouble breaking windows. Enjoy these links. Update*** This Emergency Escape Tool was tested by a Canadian volunteer fireman. Video of him testing this breaker, a Gerber knife (carbide) and a ResQme (carbide) was added.
