Yeah, knife and light are about as bare as I would ever want to go.  
If I am gonna carry only one firestarter, it needs to be something I can use any time, under most conditions.
Good points otherwise, the sharpener and all the rest are easy enough to tote, just not what I think I really need to have.  If you got em, tote em.
Safety pins are no problemo through the airports, unless maybe you got a hundred of them, or they are the really big ones.  The ones I'd have on me would be just big enough to do a diaper, or hold a hole in my breeches shut.  Paper clips do have other uses, but not anything I really need more for EDC (hmm, now I have to think about that, maybe there are some uses I might be overlooking....)
