Kershaw Iridium
Kershaw Iridium Series - DuraLock Folding Knives
The Iridium lineup centers on one feature: DuraLock. Kershaw's crossbar lock operates with a handle button—pull back to release the blade. It's ambidextrous, secure, and eliminates the pinch risk of traditional liner locks. Combined with KVT ball bearings, the action is so smooth that people specifically mention it.
The series ranges from mini to full-size, encompassing manual folders and automatics. Standard Iridium models feature 3.4-inch blades, while Mini versions are reduced to 3 inches for lighter carry and weigh 2.5 ounces. The Launch Iridium, made in the USA, offers automatic deployment with a 3.45-inch blade.
Blade steel varies by model. Most manual Iridiums use D2 tool steel, which is wear-resistant and capable of good edge retention, although it requires attention to prevent rust. The Launch Iridium runs CPM MagnaCut for superior corrosion resistance and toughness. Premium variants step up to M390 or S35VN for those wanting top-tier performance.
Blade shapes include a spear point for general use and a reverse tanto for tasks requiring a reinforced tip. Standard spear points work for everyday cutting, while reverse tanto configurations offer more tip strength for piercing or detail work.
Handle materials range across the lineup. Aluminum models keep weight down and are available in various anodized colors, including gray, black, and ice blue. The Launch Iridium G10 pairs G10 front scales with aluminum backs for texture and grip. Carbon fiber versions reduce weight further while adding visual interest. Titanium models provide durability and a different aesthetic. Special editions feature patterns such as TOPO and various limited colorways.
Kershaw’s attention to quality is evident across the Iridium lineup. Most manual Iridium models are designed in the USA and manufactured in China to maintain value, while the Launch Iridium automatics are proudly made in the USA. Every model features a reversible deep-carry pocket clip for ambidextrous use, and the DuraLock mechanism with KVT bearings is consistent across all variations, ensuring a reliable experience for every user.
The Mini Iridium series mirrors the full-size options in a more compact package. At 3.9 inches closed versus 4.5 inches, the difference matters for pocket carry. Mini versions are available in spear point and reverse tanto styles, with options for aluminum, titanium, and various colors.
Color and finish options range from practical to eye-catching: all-black tactical configurations, two-tone blades with stonewashed flats and satin grinds, ice blue with gold accents, working finishes that conceal wear, and BlackWash for a worn appearance. Bronze, clear, and black anodized backspacers add subtle detail.
The Iridium works because its fundamentals are solid: smooth opening, secure lockup, reasonable steel, and a slim profile that carries well. Whether you prefer a budget D2 folder, a premium M390 version, or a USA-made automatic with MagnaCut, there's an Iridium configuration that suits your needs.
