Product Description
The Spyderco ButtonUp C275CFPS is a first for Spyderco — the brand's first-ever manual-opening Button Lock folder, designed by Eric Glesser. The ButtonUp combines a high-strength Button Lock with ball-bearing pivot washers to produce one of the smoothest, most fidget-friendly folder actions in the Spyderco lineup. Carbon fiber/G-10 laminate handle. Reversible hourglass clip for left or right tip-up carry. 8Cr13MoV full flat grind at 3.27". At $75.00, the ButtonUp is the entry point to the Spyderco Button Lock platform — and it earns its place there.
The blade is ground from 8Cr13MoV — a Chinese stainless steel that delivers a reliable balance of edge retention, corrosion resistance, and ease of sharpening at an accessible price point. The full flat grind runs from spine to edge across the full blade height, maximizing the cutting geometry for slicing performance. The modified clip point profile provides a controlled, versatile tip suitable for everyday tasks alongside the generous primary edge. Satin finish keeps the blade clean and field-appropriate. Eric Glesser's design brief was simple: bring the Button Lock mechanism to a manual folder with the smooth, satisfying action that the Spyderco platform demands — and the ball-bearing pivot washers deliver exactly that. Spyderco describes the ButtonUp as "fidget-friendly" for a reason.
The handle is constructed from carbon fiber/G-10 laminate scales — not solid carbon fiber, but a laminate that combines the visual character of carbon fiber with the structural reliability of G-10. The open-backed design makes the handle lightweight and easy to clean. Nested stainless steel microliners around the pivot and lock reinforce the handle structure where it matters most. The reversible hourglass clip anchors to a second set of microliners at the butt end of the handle and straddles a lined lanyard tube that accommodates fobs and lanyards for retention. Reversible for left or right tip-up carry without modification. Made in China by Spyderco.
