The pointed scissors are probably not a good idea. They may make it through, but if they are hand checked they will not. The TSA specifically prohibits anything that is pointed or sharp, leaving them much room for interpretation. I have had a TSA agent even try to poke his hand with my EMT shears, just to show himself that they were not too pointy.

I have also had a discussion about the UCO stormproof matches. They made it, but I had to show the agent that they required a striker pad to ignite.

As for tinder, cotton balls and petroleum jelly can go, but you may want to keep them unmixed for the flight. A small tube of jelly used for lips will make it easily enough.

I like small saws for survival kits, but the last time I flew I noticed they had banned all saws. They used to not be a problem. You may want to check.
