Stainless steel wire, a couple of matches, fresnel lens, small pocket knife, sewing kit, small aligator clamps, safety pins, magnets, duct tape, a pencil, fishing line, a scalpell blade (sterile), a razor blade, a mini bic, a pair of tweezers, a small ferocerium rod with a piece of hacksaw blade as striker and some cotton as filler(and maybe tinder). The bigger ones also contain a tealight candle and a BCB wire saw and a few Micropur tablets. Around the tin are a couple of rubber bands cut from old tire hoses.
I used to carry sutures but eventually ditched them as the they are contraindicated in most cases when I could use them.
