Zak Tool No. 57K Key Ring Window Punch, Anodized Aluminum, Classic, Cranberry

Breaks out windows like a champ. I use a carabiner and 1" keyring to keep it on my bunker gear and it keeps it handy for extracating patients. Be warned, I had one of these before and it magically disappeared lol. Also, wearing it inside fires has been ok but be warned that with all that water and nasties flying about, you will need to thoroughly wash and dry it and I would go so far as to coat it with some WD-40 or something of the like to keep it from rusting.

Works Perfect

Vaporizes Windows

A good tool. I gave it 4 stars as the tool does bend at one end. I thought the shaft was full metal. Still a good tool to have in case of an emergency to break a glass car window.

Just what I needed

I've tried a lot of punches and these are the best. You can get a LOT of pressure applied on the point especially if you put a paracord loop through the triangle for a better grip. These work first time unlike a lot of the spring-loaded center punch kind or the ResQME, which do work, but sometimes take multiple tries and can result in cut hands due to pushing on the glass. If yours or someone else's life could be on the line don't skimp...these WORK and it's much easier to control the breakage so you are less likely to be cut, making these SAFE.

First test it broke.

Superior window breaker, breaks all car windows easily with minimal effort (all you have to do is pull the spring back and let it slap forward), and it allow you to break windows without getting your hands or arms cut in the process. I believe even kids or senior citizens can use this with relative ease. The construction and quality of the metal and machining is very good.
