Sturdy fixed blade knife, probably of 5160, tuff and easy to sharpen, sheath
Fire Piston
light aircraft cable
chunk of heavy mill plastic
Roll of heavy braided fishing line
hooks and a couple needles with eyes big enough for the line
all except 18 and knife, folded inside one of those large camp kit kettles with the frying pan lid

Fire piston is a small cylinder and plunger that lights tinder by compression. Simple, compact and it works easy.

Plastic over a hole makes a simple effective solar still to make clean water. Set pan in center of hole, spread plastic over the top, place small rock in center to cause it to dip over pan. Stick vegetation, saltwater, mud, dirty water, pee, anything with moisture in under edges into hole. Heat causes it to evaporate, then it will condense run to center and drip into pan.

roll of light aircraft cable. Snares, they hunt 24 hours a day 7 days a week. No need for lock clips, a small loop then a piece through it and the end through second piece will make it lock.
