If I may join here, I have a few differnt ideas. First I am not sure psk = personal survival tins, but if that is correct, you might find some of this interesting.<br><br>I use a very tight fitted candy tin the round ones with the dome top, and the bottoms tend to dome up.<br><br>I force the bottom back so both top and bottom are about equal, and wax the seal for better water tightness.<br><br>I don't believe in lighters or matches for being out in the woods becase they can go bad or run dry, so I have in the tin a flint and steel which would be hard to ever wear out. I also keep a small glass lens in the tin, along with jute twine coiled up. That is about 20 feet unwound. I use the just about 3" long frizzed up for tinder. Sometimes I use pre charred cotten from house hold rags to catch the spark, but I also keep a few small pieces of charred tree fungus to catch the spark from several different types of trees. I try to keep a candle stub which with a bit of charr, I can light directly, and also reseal the tin after making charr.<br>To make the charr from cotton or fungus you start a fire and do what ever you started the fire for. While the fire is burning you add the materials to be charred as you can to the tin, then with the cover loose, and a stick handy to pull the tin out when the smoke stops emitting from the seal area make the charr. <br>Sometimes I add to or take away from what is in the tin. I add splinters of fat wood if I have any, and usually a few needles can be found there. <br><br>My tin has gone swimming a few times, but seems to stay tight. I don't mess up good needles to fish, but I have used the jute for small brook trout with a hook made from twiggs, and chips of bone if I find any droppings from owls, or other small preditors. If that is the case the the bone is sharpened to a point, and lashed much like a mini hangsmans noose to the forked twigg with jute, and waxed. I find the white bone looks like a insect larva to fish, and no other bait is needed.<br><br>Well dinner has been called, and I know better to push the Missuse too far...... Mac
