Description Originally, the Spyderco UK Penknife was developed as a response to the strict knife laws in England, which prohibit the carrying of knives that can be opened and locked with one hand. Spyderco made a virtue out of necessity and presents the first Slipjoint knife of the extremely corrosion-resistant Salt series. The nitrogen-enriched blade made of LC200-N has the Sypderedge serrated edge and opens classically with a thumb opening and does not lock. The bright yellow FRN handle fits perfectly in the hand at all times. With a convertible clip (tip-up / l r).
