This was the kavanaugh Mark 1 BOB. Mountain Dew will flush wounds,chili peppers sterilize anything and peanut butter makes an expediant poultice. In the Rambo knock off there is 6' of monofilament line for fishing and a harpoon for Stellar Sealions which doubled as a sewing kit. The mark 11 kit is now waterproof, thanks to a box of emergency candles that melted. My current, mark 111 unit is under review.
