Maybe the battery end cap of the flashlight could be used as the bearing for a bow drill.
Also, in the end cap mine has a small spring. I believe I could bend that into a usable fish hook.
I read all the time about not burning batteries. Maybe they could be thrown in a fire and explode as another way to signal for help if you were sick or injured, and unable call out?
Could the flashlight tube, with the head and end cap removed, be drove into the ground, and then pulled out to clean out the dirt. Then put it back into the hole it made, and maybe have some what filtered water seep into the tube? This might work where you have mud but no water.
Small wires in the radio could be used to attach between a hook made from the antena and cordage made from the surrounding area you are in. It would make the bait and hook look more natural to a fish as the wire is strong but smaller in size. Basically a wire leader.
Maybe if you have a short stubby antena, it could be taken apart to find a large amount of coiled up wire in it.
Some where in the radio there should be wire coiled up to be used as a snare or wired leader. Even if the wire is fine, double it up several times to make braided wire and make it even stronger and more durable.
