WOW!  WOW!  You people Rock!  I just told my GF that over 400 people have read my 1st post in what 2-days?  And such good suggestions.  
That Steel Money Clip sounds like a good idea for a striking source for my Flint.  But would my Flint actually make it thru the X-ray without suspicion?  I have nothing to hide, but I'd hate to lose it.  
I even thought about the prong on your belt, ripping that peice of metal out might make a spear of sorts in dire need.  LOL  
I'd add dental floss too.  I wonder about the fishing line though, as that's borderline weapon material as in a garrote.  
Sewing needles I can see those being tossed by the guards for sure.  I tend to believe an eye glass repair kit might not make it either, those tinny screwdrivers are still kinda sharp.  
A Magnifying Glass, now that's a good backup Fire Starter!  Great idea,   I have a 2" x 6" magnifying sheet in my 1st Aid Kit.   Campmor makes a really cheap combi gadget though might look like a 'geek'  (LOL) carrying this in your pocket on a sunny hot day.   I gave this to my Nephew who's going on Eagle Scout.

Thanks again people.  What'd did ya' all think about that movie The Castaway?   He was in dire need of a good simple 1st Aid Kit, coral reefs ouch!
