Do you carry a pocket knife at all times?

A pocketknife comes in handy for sooooo much more than stabbing someone trying to hurt you. I use my pocketknife to open letters, open candy wrappers, as an impromptu screwdriver, for cutting food if I don't have a butter knife, to pick locks, to cut string, to fix a frayed shoelace...

@BlueMetalChick: They're very versatile.

@BlueMetalChick: to cut a lemon, or start to peel an orange. Cut avocados and mangos, digs dirt out from under nails, cut string hanging from hem, cut the netting under sod.... you're right! So much more!

@rottenrobi: Well I use a guitar pick to clean under my fingernails.

sounds about right.
