Originally, I had secured a long, slim nylon zip pouch on the front of my BK7 (and BK9 & Battle Rat, too!) this held a very extensive kit, but I realised I was also carrying an equally extensive pocket kit too, so Ive gone the way of the Altoids tin kit too.
My contents are still being finalised, but so far Ive also ranger-banded a space blanket under the pouch then wrapped it in about 20ft of Paracord ending in leg-ties.
Altoids tin contains Sparkrite & tabs, Mini-bic, Vaseline/Cotton balls, LED light, Magic birthday candles, Water purifying tablets, vulcanizing fluid, dental floss, thin nylon cord, scalpel blades, superglue, button compass, sewing kit, fishing kit, large hook, heatshrink tube, matches, lifeboat matches, snare wire, duct tape, wire saw, whistle, aluminium foil, fresnel lens, plasters, mirror, mini-lightstick, dog-tag with my details on one side & small pic of girlfriend (bless 'er!) in her er..."skimpies"

on other side, p38 copy, plasters, piriton & nurofen, large needle, curved needle, safety pins.
On the elastic of the pouch Ive got a green traser glow ring with a short drilled section of hex-wrench to open the handle scales on a small split ring.
Inside the handle scales Ive got another scalpel blade, more vaseline/cotton balls, matches & short piece of flintbar.
Im toying with the idea of removing the centre of the handle to make one large compartment, maybe to hold a plastic vial, and obviously Id fill in the holes in the handle scales with epoxy & just secure the grips with 2 rather than three hex-bolts.
