OK, a fishing kit for survival is a gimmick. I'm hoping to go camping this summer, and the only decent National Park I could find is actually an island in one of the great lakes. So, it makes sense that fishing might actually be useful!

I'm using an Altoid tin to keep my "survival" fishing kit. So far:
Hooks - 3 small, 1 med, 1 large
Flies - 2
Lures - 2
Weight - 4
Line - about 40 feet of 20#, in 2 different spools
1 book of MRE matches
10 staple gun nails (to secure a fish for cooking to something)
10 ft. orange 550 cord (can never have too much!)

Now, given that I have quite a bit of room left, I turn to the readers for more suggestions! Any ideas on what other fishing gear to pack would be appreciated. I'm also toying with the idea of keeping a few PSK type items in here, just in case I lose the PSK.

So, your thoughts and feedback is appreciated!
Edit: I meant that first sentence to ready "... usually thought of as gimmicks." Kind of like that kit in the SOL by AMK.
