The Spyderco ButtonUp CF PS 3.27" BLK folding knife brings Spyderco’s first manual-opening button lock design to a sleek everyday carry package. Its modified clip point blade is crafted from 8Cr13MoV stainless steel with a full-flat grind and a non-reflective black oxide finish, delivering reliable cutting performance with a partially serrated edge for versatile slicing tasks. Smooth carbon fiber/G-10 laminate scales and ball bearing pivot washers work with the button lock to provide a secure, easy-to-control action.

This ButtonUp model is well suited for everyday carry, range use, and general utility cutting where a compact, lightweight folder is preferred. The reversible hourglass pocket clip supports left- or right-side tip-up carry, while the lined lanyard tube offers additional retention options. Thoughtful ergonomics, nested stainless steel microliners, and refined hardware reflect Spyderco’s reputation for practical innovation and careful craftsmanship.
