🔪 Spyderco ButtonUp Carbon Fiber Combination Edge: Smooth Button-Lock Action in a Lightweight EDC Design 🔪
The Spyderco ButtonUp Carbon Fiber Combination Edge 3.27" Folding Pocket Knife (C275CFPS) is a sleek, smooth, and highly practical folding knife designed by Eric Glesser. As Spyderco’s first-ever manual-opening button-lock folder, the ButtonUp brings together a high-strength button-lock mechanism, ball bearing pivot washers, a full-flat-ground 8Cr13MoV stainless steel blade, and lightweight carbon fiber/G-10 laminate handle scales for a stylish and functional everyday carry knife. ✨
The ButtonUp stands out immediately because of its manual-opening button-lock design. The button-lock mechanism gives users a convenient, secure, and easy-to-operate lock system, while the ball bearing pivot washers make the action exceptionally smooth. This combination creates one of Spyderco’s most engaging and “fidget-friendly” folder actions, making the ButtonUp enjoyable to open, close, and carry throughout the day. ⚙️
The blade is a 3.27-inch modified clip point crafted from 8Cr13MoV stainless steel. This blade steel is a practical everyday choice, offering a strong balance of cutting performance, corrosion resistance, and ease of maintenance. The modified clip point blade shape provides a useful tip and versatile cutting profile, making it well suited for daily tasks like opening boxes, cutting cord, slicing packaging, and general utility work. 🔪
This version features a Combination Edge, giving users both plain edge and serrated cutting capability in one blade. The plain portion is useful for clean slicing and controlled cuts, while the serrated section adds extra bite for tougher materials. For anyone who wants a versatile pocket knife that can handle a wider variety of everyday cutting tasks, the combination edge design adds practical flexibility. ✅
The blade also features a full-flat grind, which supports excellent edge geometry and efficient slicing performance. With a blade thickness of 0.118 inches, the ButtonUp provides a strong yet practical blade profile that balances everyday cutting ability with durability. The blade length measures 3.27 inches, with an edge length of 2.71 inches, giving users a capable cutting surface while keeping the knife comfortable for daily carry.
The handle is built with smooth carbon fiber/G-10 laminate scales, giving the knife a refined look while keeping it lightweight and practical. Carbon fiber styling adds a premium appearance, while the G-10 laminate base helps provide strength and stability. The open-backed handle design makes the knife easier to clean and helps reduce weight. 💪
Spyderco reinforces the handle with nested stainless steel microliners around the pivot and lock. This construction supports the lock system and adds structural strength without making the knife unnecessarily heavy. A second set of microliners is nested in the butt of the handle to anchor the pocket clip securely.
Carry is simple and convenient thanks to the reversible hourglass clip, which allows for left- or right-side tip-up carry. This ambidextrous clip setup makes the ButtonUp more versatile for different users and carry preferences. The tip-up carry orientation keeps the knife positioned for quick access when you need it. 📎
The clip also straddles a lined lanyard tube, allowing users to attach fobs or lanyards for added grip, personalization, or retrieval convenience. This small detail adds extra usability for anyone who likes to customize their everyday carry tools.
Despite its capable size, the ButtonUp remains very lightweight. It has an overall length of 7.68 inches, a closed length of 4.43 inches, and weighs only 2.1 ounces. That makes it large enough to provide confident cutting performance while still feeling light and comfortable in the pocket. ⚖️
