Spyderco Buttonup 3.27" Carbon/Black Serrated

Spyderco Buttonup: Refined Everyday Carry

The Buttonup represents Spyderco's commitment to thoughtful design and practical functionality. This knife is built for those who appreciate quality without unnecessary complexity.

Blade and Steel

The 3.27-inch blade is ground with a full-flat profile, creating an efficient cutting geometry that works well for general tasks. The serrated edge provides reliable grip on tougher materials—rope, webbing, and similar items that can slip on plain edges. The blade steel is 8Cr13MoV, a stainless steel that balances edge retention with ease of maintenance.

Handle Design

Spyderco combines carbon fiber with G-10 laminate scales to create handles that are both lightweight and durable. This pairing delivers excellent grip in various conditions while keeping the knife trim and comfortable in the pocket. The button lock mechanism is intuitive and reliable—a single press releases the blade smoothly.

Practical Carry

At 3.27 inches, the Buttonup occupies that sweet spot between capability and discretion. It's substantial enough to handle real work, yet compact enough for everyday carry without bulk. The refined aesthetics make it equally at home in professional or casual settings.

A Knife That Works

This is a knife for people who use their tools. The Buttonup doesn't demand attention—it simply performs when called upon.
