The origin of the sheepfoot-shaped blade has been speculated to stem from mariners who found its rounded tip advantageous In preventing accidental stabbings while working on ships In turbulent seas. It's also believed that commanding officers preferred sailors to carry knives without pointed tips, especially In port to prevent altercations. Spyderco rescue knives, long favored by seafarers, have gained popularity among rescue workers, EMTs and ranchers-those who often need to cut around flesh In emergencies. The Atlantic salt, a modified rescue model, is constructed with ultra-corrosion-resistant H-2 steel. Its hollow ground blade, In SpyderEdge format, delivers exceptional cutting performance In both fresh and saltwater environments. The molded FRN handle features a shackle key and comes In either black or bright yellow, offering a reversible black-coated titanium pocket clip for left or right-side tip-up carry. For added security around water, where retrieving a dropped knife can be challenging, we recommend attaching a thong or lanyard cord to the lanyard hole.
