Spyderco ButtonUp Black Carbon Fiber/G10 Laminate Satin CombinationEdge Folding Knife [C275CFPS]

The Spyderco ButtonUp [C275CFPS] is a manual-opening folding knife with a push-button lock. This version pairs a black Carbon Fiber/G10 Laminate handle with a satin 8Cr13MoV stainless steel blade and a combinationedge (partially serrated) cutting edge.

Manual Opening and Button Lock

Eric Glesser’s ButtonUp design combines a button-operated lock with a ball-bearing pivot. The blade opens through Spyderco’s round opening hole; pressing the lock button releases it for closing. The button operates the lock rather than firing the blade, so this is a manual folder.

Blade and Carry

The modified clip-point blade has a full-flat grind. Its combination edge places serrations alongside a plain cutting section. A reversible hourglass pocket clip supports left- or right-side tip-up carry, and the lanyard opening provides another attachment option.

Handle Configuration

Smooth carbon fiber/G10 laminate scales give this version its layered handle construction. The open-backed handle leaves the interior accessible for cleaning. The blade has a satin finish.
