File the barb of the fishing hook to make an emergency wound stitching needle. Or, pack an actual medical stitching needle. This is why I love the crimping pliers on my SAK.
Sewing needle: most vic scales got a hole for a needle at the cork screw. You can put a needle in there. I made a second hole there and got a sewing needle as well as a normal needle with me. A length of thread I stuffed under the cork screw. Fire Steel: I roughed up the back of the large blade, so I can create sparks without opening a tool.
What you scratched against the file to make the fire was a ferrocerium rod, not flint. Flint is a kind of rock. It won't produce sparks when you file it. Flint produces low-temperature sparks when you strike it against a carbon steel.
Probably too little to be realistically useful, but you probably could squeeze in a useful amount if it was braided fishing line. Get the real light and thin stuff, and it won't stay in the coiled shape as much either, which monofilament line definitely does. You really only need to squeeze about 10 feet of line to be useful for an impromptu fishing situation, maybe a bit less.
Most of these trips are useful 😅 but it is fun to know. I can't imagine to survive with that knife even when an asteroid destroy the earth and had to depend on it😂
One drop of water on the striker and nope. Luckily you'd have that 11/32 of an inch of ferro rod. 😊 Good concepts, I just think there are better options.
