The Spyderco ButtonUp Carbon Fiber/G-10 Partially Serrated Folder (brand part no. C275CFPS) is Spyderco’s first manual-opening button-lock knife, designed by Eric Glesser to combine a high-strength lock mechanism with ball-bearing pivot washers for one of the smoothest folder actions the company has produced. Spyderco grinds the modified clip point blade from 8Cr13MoV stainless steel with a full-flat grind, and this version adds partial serrations along the spine of the edge for extra bite on rope, webbing, and other fibrous material. The lightweight, open-backed handle combines carbon fiber and G-10 laminate scales reinforced with nested stainless steel microliners, and a reversible hourglass clip lets you set up left- or right-side tip-up carry. Among our pocket knives, the ButtonUp suits EDC carriers who want a genuinely fidget-friendly action with added cutting versatility.
