The Spyderco ButtonUp Carbon Fiber/G-10 Plain Edge Folding Knife in Black (brand part no. C275CFPBK) is Spyderco’s first manual-opening button-lock folder, designed by Eric Glesser. Spyderco pairs a high-strength button-lock mechanism with ball bearing pivot washers for one of its smoothest folder actions, then grinds the modified clip point blade from 8Cr13MoV stainless steel with a full-flat grind.
