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. The black micarta handle with red spacers fits perfectly in the hand and also has a smasher at the end. It maintains the necessary zipper on its spine to guarantee grip while making fine cuts. Its blade has a pronounced notch to scrape the firesteel and spark out very easily. Its steel is Böhler N-695 capable of perfectly cutting any material that gets in its way. This version includes a Kydex sheath (self-made) with Tec-Lock adapter, flint holder and flint. Please note that the Kydex sheath cannot be purchased separately because each piece is molded with its own Kydex sheath to avoid looseness and maintain a perfect fit to the sheath. The Cudeman JJSK1, the best friend to face survival.
