Your absolutely right, it's a very basic kit. All the components are usable except the saw. Personally I don't bother much with wire saw's. Especially as anyone with half a brain has a SAK/Leatherman/Gerber et al with a saw on them. Having said that: I have them in my kits as an option for sawing through something that I cannot get at with a conventional saw. You just have to understand that they are vunerable to kinking and gets trapped. Which is when they snap. Just respect their limitations.

If anyone is interested, there is a much better kit based around a G.I. Match case. It has 3 decent (Now that was a surprise!) matches, a striker board and one hook with a reasonable amount of line. There is also a small "signal" mirror in the cap. Being intrigued I ordered two of them. Its childs play to add:
2 x Tinder-Quick.
1 x Button compass of the type used in Doug's P.S.K.
1 x MP1 tablet.

It's not much but it's all you need for an 1-2 day situation.
