This Spyderco ButtonUp is an everyday carry folder built around a smooth button lock and ball-bearing pivot washers. The black-coated 8Cr13MoV stainless modified clip point blade takes a full-flat grind for clean slicing on boxes, cord, and daily utility cuts. A deep finger choil and Spyderco Round Hole keep control easy when you open or close the knife.

The open-backed handle uses smooth carbon fiber/G-10 laminate scales with nested stainless microliners at the lock and clip. A reversible hourglass clip gives left- or right-side tip-up carry, and a lined lanyard tube is ready for a fob. Designed by Eric Glesser as Spyderco’s first manual-opening button-lock folder.
