The handle is well-designed, affording a solid and comfortable grip that's basically asking you to put it to use. The 0512's automatic opening is solid and consistent with a unique button actuator that showcases an anodized titanium ring. Built for serious use, the ZT 0512 is a pocket knife made for those with zero tolerance for using sub-par cutting tools.
