Unlike any other blade design, the SOG JetEdge Knife showcases new grind lines along with a "shark tooth tip" which generates exceptional point strength. SOG's preferred opening slot fits within the contours of the blade and provides quick one hand opening. A scalloped thumb rest increases downward pressure and offers delicate tip control for precision work. These unique features combine to make the SOG JetEdqe Knife one of the most advanced technical folders in the world today; for the outdoorsman as well as the professional. The half serrated ATS-34 blades of the SOG JetEdge Knife are surgically sharp. ATS-34 is considered to be a custom, quality stain resistant steel that exhibits excellent edge holding, toughness and hardness.
