Here is what i carried 2 corks, the synthetic wine variety. Hollow one out all the way to one end leaving a bottom on it. Cut the second cork off at about 1/4 of the way down to use as a top. Hollow that out. Inside I kept - Piece of a ferro rod 4 needles +50' of 20# test Braided Line Couple Lead Split Shot Few various sized small hooks and 2 larger hooks 3" piece of 16 gauge 18k Gold round wire wax couple pieces of trout bait (looks like playdoh) tin foil plastic wrap How it all fit together. Needles and ferro rod were wound together with the braided line. Used a drill to accomplish this and to get a nice tight wrap. The wax came into play here. Taking a candle and lighting it, then running the line through the wet wax as you wound it over the rods and needles makes for a nice and tight wrap when you are finished. The wax, although minimal, could be removed from the line by pulling it through a fingernail or other object and repurposed. Trout bait was flattened out into a paper thin configuration. So it wouldn't dry out, wrapped it in plastic wrap, then put the small square of tin foil around it. wrapped the whole thing in a calendar form and fit it around the braided loom. Sinkers and hooks were loose in there. the gold rod was for the keychain aspect of it and as a monetary value feature in an emergency situation. Since it is gold and wire, could be used in some medical situations too. It was bent in half with a ring me in the center. Through the top of the cork top and through the bottom of the main cork barrel. as the 2 pieces exited, Bent 90º facing each other like a staple would form. When on a keychain it was secure. Take it off, and you have a removable top. safety pins, you can normally find them on either side of my inner pant legs near my shoes. On the inner part of one of the seams as to not interfere with normal use of pants. At one point I was taking the safety pins and bending them 90º, wrapping a needle onto the inner shank using thread until the whole needle was covered. \\ Buttons I do as the manufacturer does on a nice new shirt. I sew in spare buttons on clothes that have or need them. My thought on the hooks is this. You can easily catch a small greedy fish with a small hook and a piece of the trout bait. Use it as a meal or as a bait for a larger wiser fish. The young tend to be an easier catch. Line could be used to sew clothes, wounds, used as trip wire or binding for other projects. The possibilities are endless. Being it is 20# makes it far superior to just carrying thread. Cork used as a floater. USAGE - I have in the past used all of the things in there. TSA was ever so nice to relieve me of it on a trip at one point. They were 'in' enough to let me remove my gold wire out of it once I explained what it actually was. All the other things were a no no.
