Cudeman JJSK-1 Survival Knife w/Kydex Sheath

Designed in 2013 by Juan Jose Sánchez (founder and director of JJ Adventure), the Cudeman JJSK1 is a purpose-built fixed-blade survival knife that combines practical features with durable construction. The 12 cm satin-finish clip-point blade has a vaciado ground profile, measures 5 mm thick and includes spine jimping and a pronounced notch for use with the supplied firesteel. Böhler N-695 stainless steel hardened to 59–60 HRC provides reliable edge retention and corrosion resistance for extended field use. The full-tang blade is matched to a 12 cm black Micarta handle with a red spacer, secured by stainless Allen fasteners and an internal brass threaded sleeve. The handle includes a glass-breaker pommel and ergonomic detailing for secure handling during outdoor utility tasks. Each knife comes with a custom-moulded black Kydex sheath, a Tek-Lok adapter, a dedicated firesteel holder and a ferrocerium firesteel. Each sheath is individually moulded to its knife for a precise fit and stable multi-position carry and is not available separately.
