I’ve been meaning to write this one for quite some time.
What’s on YOUR keychain?
I’ve had useful stuff on mine for a long time now. I only keep two keys on there (car and apartment), so it’s way too small and I’d lose it unless I had something weighty on there.
For a few years I had a mini Maglite torch

But then I got a cell phone with a flashlight, so I removed it and put a mini leatherman knockoff on there.
Then i lost that one, and had a regular pocket knife for a while.
Finally I switched cell phones (anyone else get tired of using the same for more than a year?), and once again needed a flashlight handy.
This time I find a mini leatherman knockoff locally, with a mini led torch hidden in one of the handles. It’s slightly larger than I like, and comes in a small pouch, but I’d rather be caught WITH a Phillips screwdriver and a torch, than without…

So, what’s on your keychain?
And since so many geeks would say: USB thumbdrive, I’ve included a link to a discussion about what geeks keep on it:
What’s on your USB drive
The main link there is to a list that’s wonderful for IT support people. It’s just amazing how poor shape regular users leave their computers in, and I think I need a larger thumbdrive in order to be able to fit all this stuff:

Finally, I think the time for me to only have a USB thumbdrive is over (or even worse, I usually only have an MP3 player filled with music).
I think I need to get my boss to shell out for one of these:
