The Kershaw Project ATOM Interval brings a fresh and forward-thinking approach to everyday and tactical carry, delivering a lightweight fixed blade that blends durability, innovation, and practical design in one impressively modern package. Created by Kershaw Originals, the Interval takes the bold spirit of Project ATOM and presents it in a larger, more capable form factor—yet it remains astonishingly lightweight. At just 0.7 ounces, this knife feels almost impossibly light in the hand, making it an ideal companion whether you’re navigating daily tasks or preparing for unpredictable situations.
The 3.5-inch drop point blade is crafted entirely from PA-66 nylon reinforced with glass fiber, a material significantly stronger than standard glass-filled nylon. This advanced build gives the Interval excellent rigidity while keeping its weight to a minimum. Since the blade features a blunt edge and contains no steel, it’s designed for use as a last-resort defensive tool where a sharpened edge might not be appropriate. The pointed tip provides tactical capability, while the smooth, plain blade profile offers a clean, modern look that sets the Interval apart from traditional fixed blades. With a blade thickness of 0.15 inches, the knife maintains a solid and stable feel during use despite its ultralight construction.
The handle continues the theme of strength, simplicity, and ergonomic comfort. Made from the same PA-66 and glass-fiber blend as the blade, it delivers consistent durability throughout the knife’s full 7.4-inch length. At 3.9 inches long and 0.38 inches thick, the handle fills the hand better than you’d expect from a tool that weighs less than a single ounce. Its clean black profile and streamlined shaping make it easy to grip securely while still keeping the knife compact enough for unobtrusive everyday carry. There’s no pocket clip, but the integrated lanyard hole gives you multiple ways to carry, attach, or secure the Interval depending on your needs.
One of the defining traits of the Interval is its ability to offer a larger, more substantial presence without sacrificing carry convenience. The extended blade and handle give you greater reach, control, and comfort compared to smaller Project ATOM models, making it better suited for those who want a more commanding fixed blade that still stays featherlight. Whether carried as a backup defensive tool or as a minimalist all-purpose companion, the Interval handles its roles with confidence and ease.
This knife also reflects Kershaw’s commitment to quality and thoughtful craftsmanship. The design, prototyping, and quality control all take place in the USA, while manufacturing occurs in China to maintain affordability without compromising standards. Backed by Kershaw’s Limited Lifetime Warranty, the Interval is built to deliver long-term reliability and peace of mind.
For enthusiasts who appreciate innovation, collectors seeking something unique, or users who want a fixed blade that won’t weigh them down, the Kershaw Project ATOM Interval offers a compelling blend of modern materials and tactical design. You can pick it up at the world’s largest knife store, Smoky Mountain Knife Works, where you’ll also find the best online knife store experience. With its lightweight construction, bold styling, and versatile everyday functionality, the Interval stands out as a truly forward-thinking fixed blade.
