I just found this website, and am still assembling my very first PSK <img src="images/graemlins/laugh.gif" alt="" />, but I have been carrying some helpful gear on my keychain for years. I recently heard a locksmith say that the weight of a keyring with even a "normal" amount of keys on it is too heavy for tumblers and lock mechanisms when swinging around in an automobile. If I hold on to the jagged part of my ignition key and let the other stuff hang down, I feel his point. This unneccessarily speeds the degredation of the lock, leading to eventual failure. This could place you in a survival situation (which may or may not be a bad thing, some enjoy the trials of life).

I now keep my keys, along with the Micra, Photon II, and K-1 "Sparky" on a carabiner, so I can unclip the bulk of it and just have the ignition key in the lock. Having the tools in your pocket, you will save the lock and also lessen the potential of a scenario as Aardwolfe has described. Also, being able to unclip and separate the tools, or just take along one keyring is very convenient.
Good Luck,
Run
