I bought it because it is on SD and it is the Bear Grylls model. With this tool and the survival knowledge I've gained from watching his show, I'll never find myself in a desperate survival situation. After all, I can just cut open the carcass of a dead animal with this tool and live there until I'm rescued. I'll even squeeze the water from the dead animal's digestive track to stay hydrated. And when the US Government snatches up everyone's guns, I'll still have a knife until the 69th amendment is repealed.
That's not water you're drinking! I like your plan though, worked well for Luke Skywalker.
