The CRKT Tuna in Olive Green and Black Stonewash is a bold and capable everyday carry knife that’s built with the kind of toughness and style you can count on. Designed with a rugged aesthetic and backed by solid mechanics, this manual folder delivers reliable performance with a clean, tactical edge. Whether you're slicing rope, breaking down boxes, or taking on everyday tasks, the Tuna is ready to get to work—no fuss, no hesitation.
At the heart of the Tuna is a 3.22-inch drop point blade crafted from 8Cr14MoV stainless steel, a tough, dependable alloy that offers solid edge retention and corrosion resistance. The black stonewash finish gives the blade a rugged, worn-in look while helping hide scratches and fingerprints through heavy use. The plain edge makes it a versatile cutting tool for a wide range of materials, and with a robust 0.15-inch blade thickness, it brings more strength than you'd expect from a folder of this size. Whether you're slicing or piercing, the Tuna's blade moves with confidence and control.
Deployment is smooth and simple thanks to ambidextrous thumb studs, giving both right- and left-handed users quick access without the need for springs or extra hardware. Once open, the blade locks up securely with a solid stainless steel framelock—no play, no doubt, just dependable security when you need it most.
One of the standout features of this knife is its balanced, two-toned handle design. The front scale is made from textured olive green G-10, offering a sure grip with a lightweight feel, while the rear handle is solid black stainless steel, delivering strength and stability right where you need it. This combination provides a perfect mix of comfort, grip, and durability, and the ergonomic shape fits the hand well, giving you total control during use.
At 4.49 inches closed and 7.69 inches overall, the Tuna is compact enough for daily carry yet substantial enough to handle bigger jobs when called upon. Weighing in at 3.7 ounces, it's light enough for pocket comfort but feels strong and capable when it's time to work. The tip-up pocket clip keeps the knife secure and ready for quick access, while a lanyard hole adds carry versatility for those who like to customize their gear.
Designed by Lucas Burnley for Columbia River Knife & Tool, the Tuna reflects his signature style—functional, clean, and built for real-world utility. Every detail of this knife is geared toward performance, from the purposeful handle contours to the thick blade spine and low-profile carry.
