I'm going to REI today to buy another of Doug's AMK kits. It will be part of a birthday gift -- in addition to his MK5 knife and e-Pico light -- that's going to a hiker friend who treks every year in the Himalayas.

Buy Doug's MK5 knife and his AMK personal survival kit and read the literature that's included with it.

That'll get you 90% of the way to having, and augmenting as needed, an appropriate PSK.

Good luck.
