I'm with Jim.

I started by seeing a kit very much like this http://www.survival.com/best.htm on one of the blog sites like http://www.instructables.com/ via a link from Digg.com I would imagine (that's the best I can do, but I *do* for sure recall seeing the saw blade attached to the kit like the above link.

So I was Googling personal survival kits and checking out military aviation ones and happened upon D.R.'s homemade kit.

Then the news was broadcasting their usual FUD (this time about avian flu) and so I decided to join the boards and join the discussion about long term supplies.
