SHOP CASE KNIVESThe Three Rivers Manufacturing ATOM Linerlock Folder is a precision-built everyday carry knife that blends premium materials, clean design, and lightweight performance into a compact USA-made package. Built for users who demand reliability without unnecessary bulk, the ATOM delivers consistent cutting capability in a refined, pocket-friendly platform that’s ready for daily use.
Measuring 4.68 inches closed and 8.13 inches overall, this folding knife maintains a slim and balanced profile that carries easily while still offering a full-hand grip when open. The 3.5-inch drop point blade is crafted from CPM MagnaCut steel, a high-performance alloy known for exceptional edge retention, corrosion resistance, and toughness. With a thin .09-inch blade stock and flat grind geometry, it excels at slicing tasks, making it well-suited for everyday cutting duties such as opening packages, trimming material, and general utility work. The stonewash finish adds a practical touch, helping to mask wear while giving the blade a clean, functional look.
Deployment is smooth and reliable thanks to the thumb stud opener, allowing easy one-handed operation. The linerlock mechanism provides secure blade engagement during use, offering a straightforward and trusted locking system that’s easy to maintain. Designed for right-hand carry with a tip-up pocket clip configuration, the ATOM ensures consistent orientation and fast access when needed.
Weighing just 3 ounces, this knife is built for all-day carry comfort without sacrificing strength or control. The lightweight design makes it easy to forget in the pocket until it’s needed, yet it feels solid and capable in hand. The handle features Popsicle Purple G10 3D contoured smooth scales, giving the knife a bold, modern aesthetic paired with refined ergonomics. The contoured shaping enhances comfort and control, while the smooth G10 surface provides a secure yet comfortable grip. The vibrant purple tone adds a distinctive visual identity that sets it apart without compromising functionality.
Every element of the ATOM is designed with purpose, from its premium steel and efficient blade geometry to its lightweight construction and ergonomic handle design. It’s a no-nonsense EDC tool built to perform consistently across a wide range of daily tasks.
