To that end, the Grinder offers a blade with a slightly curved belly for all-purpose cutting and slicing. A clipped, tanto-inspired tip offers excellent piercing capabilities, too. If you need to bear down on the back of the blade during a particularly tough cutting job, the concave spine with heavy jimping provides additional grip security. The work-ready blade is made of 4Cr13MoV steel for hardness and wear resistance. Then Kershaw expertly heat-treats it to enhance edge retention and strength.
