Buck 840 Sprint Select Black — Lightweight, Ready-to-Deploy Everyday Carry Knife

Designed and built in the USA, the Buck 840 Sprint Select Black is a purpose-built everyday carry knife that blends precision, speed, and dependable performance in a compact pocket-friendly package. If you value a blade that’s light enough for daily wear yet tough enough for common tasks, the Sprint Select delivers. Made in the USA and crafted with Buck’s longtime commitment to reliability, this knife stands ready for work, travel, or outdoor use.

Fast, one-handed deployment is at the core of the Sprint Select. A smooth ball-bearing opening pairs with a top flipper for confident, flick-to-open action, while a secure liner lock keeps the blade safely in place during use. When you’re ready to stow, the blade folds to a compact 4 3/8" (11.1 cm) and slips quietly into a pocket or bag.

Precision blade for everyday chores — the 3 1/8" (7.9 cm) satin-finished drop point blade is crafted from 420HC steel, a balanced choice for edge retention, corrosion resistance, and straightforward maintenance. With a blade thickness of 0.120", the Sprint Select offers the stiffness needed for light-duty prying or scraping without adding unnecessary weight. This combination is ideal for tasks from opening boxes and trimming rope to quick food prep on the go.

Rugged, comfortable carry is engineered into every detail. The handle is glass-filled nylon in a sleek black finish, providing a durable, ergonomic grip that stays comfortable during longer tasks or outdoor sessions. A deep pocket clip ensures secure, accessible carry so the knife is ready when you need it and unobtrusive when you don’t. Buck’s heritage of craftsmanship shines through in the fit and finish you experience every day.

Why this knife fits modern life

For everyday professionals, travelers, campers, or hobbyists who demand a dependable, American-made knife, the Buck 840 Sprint Select Black answers with speed, security, and practical versatility. It handles daily chores—whether you’re cracking open packages, slicing fruit on the move, or trimming cord—without weighing you down. This is a compact, high-performance tool designed for real-world use, not just a display piece.

Care and longevity

Simple maintenance goes a long way with 420HC steel. Wipe clean after use, keep the blade dry, and touch up the edge as needed. The combination of durable materials and Buck’s proven heat-treat approach helps maintain edge life and reliable performance over time.
