Sybert777,
I have tinkered on several configurations of Pocket Survival Kits/Tins for some time now.  The configuration and contents really depend on your current situation.  I’m currently a contractor in Afghanistan and have settled on a kit based on the instructions provided with the RSK Mk5 Knife.  For the past 5 months it has ridden in the cargo pocket of my pants.   
 
 Cheers,
W-W
