You didn't mention using an EDC flashlight to avoid land mines while walking through the backyard at night ... gifts from my dear dogs.

Has anyone else here been in a restroom at work or a public place when the power went out? They don't put emergency lighting in restrooms.

Now, out of the gutter and into the parking lot ... have you ever dropped kicked your car keys in a marginally lit parking lot. That's why the EDC light doesn't go on the same keychain as the car keys.

Regarding carrying knives in the city ...

Last night I used my knife for cutting string, slicing open a bag of cotton balls (yeah, helping a bunch of scouts make firestarters), and slicing open pizza boxes tapped shut (special treat at a church lock-in - not a normal scout meal). This morning it was used for opening the plastic bag in a box of pancake mix, cuting the sealwrap off a new bottle of syrup, slicing a baggle for my son, and opening a UPS box. Its all much easier to do with a knife than a key.
