Product Review
The Zero Tolerance 0640 is a ZT/Ernest Emerson collaboration that provides both utterly practical design and boldly eye-catching style. The stonewashed titanium handle features a green carbon fiber composite overlay on both sides. In addition to the engaging green overlay, the handle also features ridged machining at the top that follows the handle's angular contours, both front and back. A sturdy frame lock with hardened steel lock bar insert provides a secure lockup. Jumping at top and bottom of the handle enhances grip. The handle is paired with a 3. 75-inch, clip-point blade of CPM 20CV high-chromium stainless steel. This powdered metallurgy tool steel offers exceptional wear resistance-and a truly long-lasting edge. This fully manual knife opens one-handed with the Emerson thumb disk. Brass washers surround the pivot for smooth operation. A reversible pocket clip makes it easy to carry left- or right-handed. The 0640's pocket clip hole pattern is also compatible with aftermarket clips from Ernest Emerson and Steel Flame.
