Doug may not be able to reveal the source of the cord, but perhaps a little research can provide a suitable alternative. According to the Pocket Survival Pak contents list the cord is "braided nylon cord" with a 150+ lb test rating. That looks a lot like mason's line. If you want to explore that option there are a lot of sources for mason's line (including your local home improvement store). Here's a link to a Froogle (Google) search for it:
Froogle search link Incidentally, I recently found a reliable source for 'parachute cord'. I can't claim they're the cheapest, but they shipped my order promptly. The "Type I Nylon" cord may only be rated at 100 lbs, but it feels stronger than higher rated cordage I've purchased in the past. It's basically a lighter version of 'traditional' 550 lb test parachute cord. It's also thin enough to thread through the lanyard hole on my Leatherman Wave tool. (

p.s. UPS is scheduled to deliver my 3 PSP's tommorow. One for my Jeep, one to carry (and experiment with) and one for the car kit I'm building for my nephew. In previous years I've given swiss army knives and photon lights as Christmas presents. This year may be the year of the PSP.
