The Spyderco ButtonUp C275CFPBK is a manual-opening folding knife designed by Eric Glesser, built around a 3.27-inch modified clip point blade in 8Cr13MoV stainless steel with a full-flat grind. Its carbon fiber and G-10 laminate handle scales ride over stainless steel microliners, giving the knife a lightweight, open-backed construction that is easy to clean.

The button-lock mechanism paired with ball bearing pivot washers produces a smooth, fidget-friendly action, while the reversible hourglass clip supports left- or right-side tip-up carry. A lined lanyard tube accepts a fob or lanyard, making the ButtonUp a practical everyday carry folder for tactical use and knife enthusiasts alike.
