The Cudeman JJSK 1 was designed in 2013 by Juan Jose Sanchez, founder and Director of the survival school "JJ Adventure". This knife was designed to break the rules of survival. With it we started to include the sharpening stones along with the signal mirror, the paracord and the firesteel to make fire without the need to carry a lighter in its full version. Its blade has a pronounced notch to scrape the firesteel and spark very easily. The sand micarta handle with black spacers, fits perfectly in the hand and also has a butt breaker at the end. It maintains the necessary zipper on its spine to guarantee grip while making fine cuts. Its steel is Böhler N-695 capable of perfectly cutting any material that gets in its way. Its brown leather sheath is multi-position with loops and rivets to carry it both vertically and horizontally and includes the adapter for stone and flint. You will not be indifferent with this piece hanging from your belt.
