Hmm, interesting question. I don't carry a mini-kit as EDC for a couple of reasons. The main one being dress codes. I work in an office environment. I'm my company's spokesman and primary new biz contact, ergo dress slacks and jacket every day. No place for a mini-kit, even if I wanted to carry one. The Sebenza raises enough eybrows

.
The other reason is plain utility. I don't see a need for one. I have on me at all times a cell phone, Sebenza (or Spyderco Lum Chinese folder), Zippo lighter, SAK, pre-paid phone card, ASP sapphire light and several safety pins (attached, like the ASP, to my keychain). I try to keep about $100 in my wallet most of the time. Should be enough to get me through any building blackout.
There's a SureFire 6P and spare batteries in my briefcase and an assortment of bandaids in my desk (thanks to New Graham!).
Despite everything that has happened over the last several months, I can't justify more than that on a daily basis.
ON THE OTHER HAND, I do keep a lot of stuff in my car. I figure if things go wrong there, I'm in bigger trouble than if the wonky elevators in my building choke.
The car kit includes: a SureFire 9N, Leatherman Wave, fire extinguisher, anti-bacterial wet wipes (also good after lunch at Sonic) and a couple of David Grisman CDs -- never know when you're gonna need some good bluegrass. In the trunk are jumper cables, gas can, funnel and hiking boots (I live in Kansas -- if my car breaks down somewhere I've got to walk, it'll probably be five below outside and I'll be wearing thin loafers).
Also in the trunk, tucked under the cargo net is a pack containing leather work gloves, bottled water, power bars, Atwater Carey Expedition first aid kit, 100' of 550 para-cord, extra socks, windbreaker, magnesium fire starter, etc. Under that is an emergency blanket, 8'x10' tarp, folding camp shovel, a couple of road flares and a cheap air compressor with flat-fixing goo.
Frankly, I just don't see the need for snare wire, fishing hooks or other wilderness survival paraphenalia -- this is Kansas, there is no wilderness. Not to say that those things are not appropriate in the right environment, but this ain't that environment. I've tailored my kit to fit the likely scenarios.
Anyway, the Altoid-style mini-kit is neat. I'm fascinated by them. But I don't carry one.
