In your pocket
 A quality pocket multi-tool
I literally use mine every day in my job as a systems administrator, and my wife has started carrying one as well.--mrbill
A multi-tool is a little bulkier than I often want to carry, and may be overkill for many people. But, I always have a small folding knife in my pocket. The tricky thing for me was finding one that was easy to open and close one-handed, but small and light enough to be inobtrusive and not cause people to freak when you pull it out. (I carry a William Henry T10, which is outstanding, but pricey.) --Kscaldef
I've lost two Leatherman keychain minitools to airport security. It's not easy to remember to remove them from the keychain before going on a flight. --Fjarlq 19:34, 13 February 2006 (EST)
 Breath freshener
Anything from a pack of gum to a package of breath strips... those new pocket pack breath strips are wonderfully small and transportable
- Be sure you don't put a metal Altoids Breath Strips tin in the same pocket as your cell phone, it tends to scratch the plastic. Plastic breath strip containers are fine. --jagtrev 01:51, 5 Apr 2005 (EDT)
 A bandana
I've had one on my pocket everytime I've left the house for the past twenty years. It can be used to wipe noses (and faces and hands), carry leaky fountain pens, scrape (and wash) icy or filthy windshields, clean glasses, hold change or marbles or other small objects, protect electronics (like an iPod), dispose of dead rodents... and that's just off the top of my head. Plus, they're cool. --JW 24 Mar 2005
Or a handkerchief in the UK. I keep a clean stack in the sock drawer. Better than paper tissues, stronger and greener. As soon as it's soiled (could be hours, could be days) chuck it in the laundry bin. I find If you have a cold, then carry a couple - more sanitary, and kinder to the nose. Smear Tiger Balm or Vick Vaporub on one for a nice decongestant. --Muteboy 11:44, 3 November 2005 (EST)
- But not as sanitary or healthy. Using a handkerchief multiple times may get you reinfected with whatever made you sick in the first place. On the other hand, handkerchiefs sure are handy! Your choice...
 A plastic squeeze coin purse
I used to dump change in my pocket which would bounce off of my cell phone, then I picked up one of these at a cheezy souvenir shop.
People always smile when they see it. I get a lot of compliments about it being cool and retro. And, now, I never hunt for coins and they don't bounce off of my cell phone. --RobNoxious 04:59, 8 Apr 2005 (EDT)
I've taken to using a small plastic bag to keep my change together, rather than jingling. --Muteboy 11:44, 3 November 2005 (EST)
