Spyderco ButtonUp

A bold new chapter in Spyderco innovation, the Spyderco ButtonUp, designed by Eric Glesser, marks the company’s first-ever manual-opening value lock design—bringing a fresh, fidget-friendly mechanism to a platform built for everyday reliability.

At the heart of the Spyderco ButtonUp is the perfect blend of form and function. It features Spyderco’s signature Round Hole opener, delivering effortless one-handed deployment, while ball bearing pivot washers elevate the action to a new level of smoothness and consistency. Whether you’re opening it for work or just for fun, the ButtonUp offers a satisfying, fluid experience every time.

But this knife is more than just fidget factor—it’s a capable and compact EDC tool. Nested steel microliners provide hidden strength without bulk, and a sturdy hourglass-style pocket clip (fully reversible for left or right carry) ensures it rides deep, secure, and discreet. A thoughtfully placed lanyard hole offers yet another layer of customization and carry flexibility.

Stylish, compact, and built to perform, the Spyderco ButtonUp proves that innovation and utility aren’t mutually exclusive—they’re better together.
