For my waist pack size PSK, I got rid of the Bic, matches and Magfire, and went with a simple 1/8" rod flint (Misch metal) and wax/magnesium impregnated cotton balls (or Coghlins tinder). I also got rid of the signal mirror and the button compass (the latter an almost worthless direction finder IMHO) and replaced both with a mirrored lid compass, like the Silva Trekker.
