Gosh, you all make me feel paranoid. Guess maybe I'm not as confident as I used to be. I used to carry a Gerber FS II with a "flipit" and a kubaton keychain all the time. Back in my "blue-target" days in Colorado, I carried either a .38 special (6.5" .357) SW or later 9 mm SW or my HK P-7 - we weren't allow a concealed weapon off-duty.
Now, living in a semi-free state, Arizona has open-carry, I carry a cute little 2.5 in Kershaw 1600VIB (the rainbow colored one), a little Leatherman Micro. My car keys are on Kubaton style pepper spray keychain like I gave my daughter. Then depending on the occasion, I clip on a Benchmark ATS-34, but for dress I replace it with the Boker ceramic, or sports-dress (bragging rights: "you call that a knife?") I take the Cuda Maxx that is considered a concealed weapon here as its a5.5 inch blade. For years, I've liked neck-knives, so about half the time I carry a Cuda Arclite. As an AZ CCW holder, both of them are legal here. Just to stay in practice, about a third of the time, even around the house to gain familiarity, I carry either the Ruger SP101 (.357), the P7, or my little target Walther P22 (it's light and just might scare off a javalina or coyote).
BTW, my significant other packs her Ruger GP100 when she's not on the M-D air farce base here (ooops the jarhead in me slipped out there).
Actually, since I'm an older person, my favorite carry is my Canemaster cane. "I'm just a poor defenseless old man, officer"; that's why I'm studying with Hock.
