Spyderco Buttonup: Refined Everyday Carry
The Buttonup represents Spyderco's commitment to practical design married with premium materials. This is a knife built for serious users who demand both performance and aesthetics.
Blade Design
The 3.27-inch blade employs a full-flat grind, a geometry that maximizes cutting efficiency while maintaining structural integrity. The serrated edge excels at slicing through tough materials—rope, webbing, and similar demanding tasks—while the satin finish resists fingerprints and corrosion.
8Cr13MoV stainless steel provides a practical balance of edge retention and corrosion resistance. This is a proven blade steel that responds well to maintenance and holds a functional edge through extended use.
Handle & Deployment
The handle combines carbon fiber and G-10 laminate construction, delivering a lightweight yet durable grip that resists wear and environmental degradation. The carbon fiber accents provide visual distinction while the G-10 ensures reliable grip in all conditions.
The button lock mechanism offers intuitive one-handed operation. Press the button to release the blade smoothly and securely. This design is favored by users who value simplicity and reliability over complexity.
The Practical Choice
This is a knife for the working professional, the outdoor enthusiast, or anyone who carries a blade as a genuine tool. No flash, no gimmicks—just solid engineering and materials that earn their place in your pocket.
