The Cudeman JJSK 1  was designed in 2013 by Juan Jose Sánchez, founder and director of the survival school “JJ Adventure.” This knife was designed to break the rules of survival. With it, we began to include sharpening stones along with a signal mirror, paracord, and firesteel to make fires without having to carry a lighter. Its blade has a pronounced notch to easily scratch the firesteel and strike a spark. The black micarta handle with red separators fits perfectly in the hand and also has a firebreak at the end. It maintains the necessary zipper on its spine to guarantee a firm grip while making a fine cut. Its steel is Böhler N-695, capable of perfectly cutting any material that gets in its way. Its black leather sheath with red stitching is multi-positional with loops and rivets to allow it to be carried both vertically and horizontally and includes the flint and flint adapter. The design of this case was the initial inspiration for creating similar cases such as the Entresierras or Ent models.
