A re-profiled (shaving sharp) Spyderco Delica in pocket and a keychain Swiss Army knife (the "Classic"?) on keychain. One of the scales recently fell off the SAK, so I'm trying out their lifetime warranty and sent it in. No word yet on what action they'll take. If it requires any out-of-pocket expense, I'll probably quit buying Victorinox and get a Leatherman Micra or something.
