Two questions for the forum.
I have recently upgraded my EDC . A new kinfe -Falkniven U2 - small very sharp, and probably won't get me busted should a police officer decide to search me, and a peakLed "snow" 3Led lithium battery torch. These items, combined with a nice leather wallet to carry them both, along with my Credit cards and cash. (Okay - the information isn't really to the point but I have to tell someone <img src="/images/graemlins/grin.gif" alt="" /> the quality of all three is excellent <img src="/images/graemlins/grin.gif" alt="" />)
Anyway these items will actually be on me, so what benefit would a small LED keychain light serve? Apart from finding a keyhole in the dark, they seem way too small to be of much use.
I hear a lot about them, and how useful they are, but no-one seems to say what for. Surely such a small light would have very limited uses, and as such not be of much practical use in an a emergency?

Lastly I came across this water filter, that happens to be an indirect link from this site. It seems like a good idea for a BOB, or even a daysack. Any comments?
