I think my FAK is very out of step with what is common here. The last time I looked through a thread on this topic there were accounts of Space blankets and carrying two shell dressings one of which would never be lent less the owner copped a 7.62 round and found he'd dished out his last one, all that kind of stuff. I don't do any of that.
Mine does change depending on what I'm doing and who I'm doing it with. It makes sense to carry flares, a strobe, Salamol, better bandage, sun lotion and so on for some events, but in the main nah.
My FAK is a misnomer really. It's better described as a bucket for mending stuff that doesn't fit elsewhere. For example little forceps live with the fishing bits so they aren't in the bucket. Similarly, I've got duct tape wrapped round all sorts of things, even the tubes I carry coffee in, so I don't duplicate it there. The same with DEET and a whistle. I know there's a bit of a fetish for duplication and for some items that makes sense [eg compass]. However the buzz word redundancy usually means to me -
a : the quality or state of being redundant : superfluity
b: superfluous repetition
c: an act or instance of needless repetition
Sure I'm aware of the military 2 is 1 and 1 is none motto, but that usually means I'll get pissed off with all of it and not carry any, so aside from a few bits I prefer 1 is 1, so pick a good one and use it wisely.
Anyway, the pic below is the bucket I've been carrying recently. It's just a few simple items to solve problems I'm likely to or will encounter.
1] Transpore tape. This is what I use to close wounds. If I cant cobble it together with makeshift butterfly stitches from this its time to go home.
2] Mircropore type tape
3] Inadine dressing [Povidone Iodine]
4]Mepitel dressing [Soft silicone wound contact stuff]
5] Gauze
6] Cotton wool
7] Tampon
8] Pills
Asprin
Tramadol [Pain]
Loperamide [stops you shitting]
Bisacodyl [makes you shit]
Ranitidine [indigestion]
Cetirizine [antihistamine]
9] Orajel [It's got Benzocaine in it so it feels a bit like putting coke on a toothache. And as I've mentioned before here if you've got your woman with you be imaginative with it.]
10] Vaseline
11] Eye bath
12] Bit of bandage
13] Magnifying glass
14] Tweezers
15] Mirror [It's a heliograph but hey, a mirror].
16] KMnO4
17] Two types of water treatment tabs.
As you can see far from extensive. Stuff like antiseptic lives elsewhere with the DEET and the bite and sting cream. Woolly wire and more cotton wool lives elsewhere with a couple of night-light candles. Safety pins live in a little box with some needles, thread, spare buttons, and a bit of bees wax. [That's actually what is immediately left of the heliograph]. So this isn't all but it should give you the flavour of where I'm at.
