The Spyderco ButtonUp (brand part no. C275CFP) is Spyderco’s first-ever manual-opening button-lock folder, designed by Eric Glesser to deliver one of the smoothest, most fidget-friendly actions the company has produced. A high-strength button-lock mechanism pairs with ball bearing pivot washers for effortless deployment and closing, while the modified clip point blade is full-flat ground from 8Cr13MoV stainless steel for a strong, capable edge. The open-backed handle uses smooth carbon fiber and G-10 laminate scales reinforced with nested stainless steel microliners, keeping the knife light, easy to clean, and comfortable for everyday carry.
