Considering this is ETS there are only few unusual items:
* Lockpicks - I decided against the pen type, not trying to hide them is less suspicious
* tiny ferrocerium rod for gas lighter - mounted it for the keychain with a spring but I consider making a device that is easier to use
* alligator clips
* WMF nomad cuttlery set or knife and fork in a credit card case
* a few neodymium magnets
* VHF/UHF handheld ham rig

The rest is just the usual stuff.
