OK, since there are so many pics you guys guilted me into making some more. Here is my little bag of evil, which goes in a bigger bag w/ other stuff...
From compass on top left: Compass, Fenix CR123 Flashlight and diffuser, climbing accessory cord, Ace bandage, moleskin, gauze and tape, AMK FAK, wound FAK, sunscreen, compressed towels, spoon, bandanna, mosquito headnet, sun/safety glasses, headlamp, paracord, stuff sack, screw eyes, fishing kit, C/F DMT sharpener, pencil sharpener, Bic, Trioxane, Storm matches, Coghlans fire stick, electrical tape, duct tape, and ranger bands on a stick.
And here is the rest of my kit that goes most places with me in an Osprey day pack. I take this stuff in a different pack for overnighters and longer, along with my tent, bag, and pad.
From top left, balaclava, MSR Dromedary bag, 1L, MSR Sweetwater filter, silnylon poncho, MSR Titan pot, spoon, spare batts, Pocket Rocket stove, fuel, TP and sanitizer in a plastic bag, MRE pb, crackers, and jelly, spare knife, handwarmer, matches, mini bic, and the pack.
I upgraded to the pack so I could carry extra bits of kit when needed, along with what is shown. Binocs, radios, camera, extra sweater, etc. It is also nice because it handles a load better than something strung over one shoulder.
I tend to keep all this together, but it is for multiple seasons and reasons, so parts of it could be trimmed if a person didn't want to carry it all. As it is, everything you see, in the pack, with a couple Mountain House, weighs 10lbs. If you need a fire, take a tool of some sort in there, for summer trips I usually carried a machete and a Bahco saw, though I quit carrying the saw after I broke it. I also take whatever water bottle I have with me at the time.
When I carried a smaller bag, I used an Aquamira filter top screwed on a Nalgene cantene to save space, and brought along the stuff in the small bag, along with the Bahco saw. Other than that, there wasn't a lot of room left for anything else, and when you did throw in binocs and a camera, the strap would start getting uncomfortable.
