The SOG One Zero XR Black + Black is a precision-engineered folding knife designed for those who demand uncompromising performance and sleek, tactical styling. Built with premium materials, advanced locking technology, and an attention to detail that reflects SOG’s reputation for innovation, this knife is as capable in everyday tasks as it is in more demanding scenarios. It’s a modern cutting tool for those who appreciate the perfect combination of form, function, and durability.
At its core is a 3.11-inch clip point blade crafted from CPM S45VN stainless steel, a high-performance powder metallurgy steel known for its outstanding edge retention, toughness, and corrosion resistance. Enhanced with SOG’s CRYO heat treatment process, the steel’s structure is refined at a molecular level, resulting in superior hardness and wear resistance. The blade is coated in a black titanium nitride finish that not only adds a striking stealth aesthetic but also increases surface hardness and reduces friction during cutting. The clip point profile offers excellent precision for piercing and detail work, while still providing enough belly for slicing tasks.
Opening the knife is quick and intuitive thanks to the integrated thumb hole, which allows for smooth, controlled blade deployment from either hand. Once open, the blade is secured by SOG’s XR lock—a rock-solid, ambidextrous locking system that’s easy to operate, extremely reliable, and built to withstand heavy use. The XR lock ensures zero blade play and exceptional safety, giving you confidence in every cut.
The handle is crafted from lightweight, durable black aluminum that offers a perfect balance of strength and portability. Its ergonomic contours and textured surface provide a secure grip even in challenging conditions, while maintaining a streamlined profile that’s comfortable to carry. The all-black design gives the knife a cohesive, professional look that blends well into tactical gear or a minimalist everyday carry setup.
Measuring 4.7 inches closed and 7.8 inches overall, the SOG One Zero XR is compact enough for daily carry yet substantial enough for serious cutting jobs. The blade thickness of .1 inches ensures a keen slicing edge while still providing durability for more rugged tasks. Weighing in at 3.9 ounces, it offers a satisfying, balanced feel in the hand without becoming burdensome in the pocket.
Carrying this knife is as discreet as it is practical, thanks to its reversible, low-carry, tip-up pocket clip. The design keeps the knife deep in the pocket and out of sight until you need it, and the reversible configuration makes it equally comfortable for left- or right-handed users.
