SOG One-Zero XR Folding Knife 3.1in Plain Black TiNi Clip Point SOG-12-73-03-57

The SOG One-Zero XR Black is a precision-built folding knife that delivers premium materials, refined engineering, and confident performance in a sleek, tactical profile. Designed for those who expect more from their everyday carry, it combines cutting-edge blade steel with SOG’s innovative locking technology for a knife that’s as reliable as it is striking.

With an overall length of 7.8 inches and a closed length of 4.7 inches, the One-Zero XR offers a balanced, easy-to-carry footprint. Weighing just 3.9 ounces, it’s light enough for daily pocket carry yet solid enough to inspire confidence when you put it to work. The streamlined aluminum handle keeps the profile slim and durable, offering strength without unnecessary bulk. Its clean black finish complements the blade and enhances the knife’s modern, understated aesthetic.

At the heart of this knife is a 3.1-inch clip point blade crafted from CRYO CPM S35VN stainless steel. This premium American-made steel is renowned for its exceptional edge retention, toughness, and corrosion resistance. Enhanced by SOG’s cryogenic heat treatment process and hardened to Rc. 60–62, the blade delivers long-lasting sharpness and dependable performance under demanding conditions. The straight edge excels at slicing, piercing, and precision cutting, while the 0.1-inch blade thickness provides a strong yet efficient cutting geometry.

The Black TiNi finish adds more than just a bold, tactical appearance. It increases surface hardness, enhances corrosion resistance, and helps reduce glare. The result is a blade that looks sharp and performs even sharper, maintaining its edge and finish through repeated use.

Deployment is smooth and versatile thanks to dual opening options. The XR lock mechanism allows for quick, ambidextrous blade action, while the thumb hole provides intuitive, one-handed opening. The XR locking system offers rock-solid lockup strength and safe, controlled closure, making operation seamless for both right- and left-handed users. It’s engineered for reliability, ensuring the blade stays secure during heavy cutting tasks.

A reversible low-carry pocket clip allows for discreet, tip-up carry on either side, so you can tailor the knife to your preference. It rides comfortably in the pocket while remaining easy to access when you need it most. Every detail of the One-Zero XR reflects SOG’s commitment to performance-driven design within the trusted One-Zero product family.

The SOG One-Zero XR Black brings together CRYO CPM S35VN steel, a durable aluminum handle, and the strength of the XR locking system in a refined, high-performance folding knife.
