Glanced over the responses and in a quick scan I did not see anything about Altoids tins. Unfortunately, I have not built my EDC altoids survival/medical kit yet but I have been setting stuff aside for a while. The altoids tins offer the advantages of being compact, non threatening, color "codeable", and they even have a mini altoid tin if you want to get really small. I plan to one day have a dedicated medical tin, a dedicated survival/hiking tin, and an EDC tin which would be a combination of the other two with maybe a little everyday "social" survival added in. On Survivalblog.com I have seen an article detailing one preppers tin entitled "The Ultimate Altoids Tin Survival Kit, by J.C.R" where he goes in depth on what to carry and why and it is pretty amazing what you can fit in there. There are also many other articles on the site (including one by myself), that detail different advantages and uses for the tins.
I don't know if it has been mentioned already or not, but there is a flashlight by fenix (fenix eo1) that is very small, very bright, and takes one AAA battery. If you go to the gun shows in Knoxville, Knoxville Tactical has these for about $10 each (which beats amazon right now), and they are great people to deal with. I keep one with my leatherman wave, one on my key chain, one in my tool chest, one in my truck, one in my truck tool chest, and have extras to spare. Another Knoxville Tactical gun show find is 5.11 Rush 24 bags. After taking a Rush 24 on a family weekend trip (with a condor attachment for a toiletry bag), I now have 3 black Rush 24s and red/reflective Rush 24. I looked and the only one I found cheaper than Knoxville Tactical was the red one that I bought used off craigslist. The red one is designed for emergency personnel and would work great for them and for hiking, but right now, i have allocated it as my car emergency bag (not B.O.B though), to keep jumper cables, some water, first aid kit, etc.
I would like to thank UncleJak for the suggestion about the leather pouches. I bought a few, realized they were too small for what I planned on using them for, but just might make a great EDC pouch.
I am not new to TGO, but until now I have mainly stayed in the trading post section. I say that to say that if I have somehow violated a policy by posting other sites and/or businesses, that I was unaware and will make changes if so informed.
