Sorry for the lack of updates, I've been traveling around the USA for the past 4 weeks. On my way, I picked up a few interesting keychain items which I plan to post about in the next few updates.
Out of interest, here's the keyring setup I was carrying for my travels:
-true utility telepen
-'mini' dogtag with name and email address (I've blanked my personal details out). These were bought from http://www.mydogtag.com
-size 0 nite-ize s-biner
I brought along the swisstech utili-key because it's light and unobtrusive. It came in handy cutting some clothing tags, and some other odd jobs. I put the keychain away in my backpack during security checks, and the utili-key managed to pass through without any problems.
The empty s-biner was used for attaching and detaching things to the keyring.
