Pros: Construction, Weight, Materials
Serious glass breaker
This item is heavy for its size, and the point is very hard and very sharp. It will break skin as well as glass. I don't recommend carrying this in your pocket, as the point will tear a hole in no time, but I keep mine in my car, in case I need to break glass or whatever else needs breaking. Don't touch glass with this thing unless you're serious about breaking it, because that's what will happen. I attached a small loop of blaze orange 550 paracord to mine to make it easier to find in low light.
