Spyderco ButtonUp Carbon Fiber Features The Spyderco ButtonUp Carbon Fiber introduces a high-strength button-lock mechanism paired with ball bearing pivot washers producing one of the smoothest and most fidget-friendly folder actions the company has produced. Designed by Eric Glesser this manual-opening button-lock design gives users a satisfying tactile deployment distinct from a traditional liner or frame lock folder. The modified clip point blade is crafted from 8Cr13MoV stainless steel with a full-flat grind delivering strong edge geometry that holds up to everyday cutting tasks. This combination of a smooth action and a capable blade makes the knife equally at home as an everyday carry piece or a collector s item. The blade is housed in a lightweight open-backed handle built from carbon fiber and G-10 laminate scales keeping the knife easy to clean while reducing overall weight. Nested stainless steel microliners reinforce the handle around the pivot and lock adding strength exactly where the knife needs it most. A reversible hourglass clip provides a choice of left or right side tip-up carry anchoring to a second set of microliners in the butt of the handle that also straddle a lined lanyard tube for attaching fobs or lanyards. Finished with a black oxide coating over the clip point blade the Spyderco ButtonUp Carbon Fiber gives everyday carriers a premium versatile folder built for smooth convenient use.
