Kershaw's Answer to the Axis Lock
The Kershaw Iridium, launched in 2024, features Kershaw's proprietary DuraLock mechanism — a crossbar lock similar in concept to Benchmade's iconic Axis lock. Crossbar locks have become increasingly popular as Benchmade's original patent expired, and Kershaw's version brings this mechanism to a more accessible price point. For EDC enthusiasts, the Iridium represents a significant release: Kershaw build quality with a modern, ambidextrous, one-hand-friendly lock at a competitive price.
How the DuraLock Works
The DuraLock mechanism consists of a spring-loaded crossbar that slides inside the handle along cutouts on both scales. When the blade is opened, the crossbar moves forward against spring tension and wedges behind the blade tang, locking it firmly. To close, the user pulls the crossbar backward with their thumb, disengaging it from the tang and allowing the blade to swing shut. The operation mirrors the Axis lock: it's ambidextrous, intuitive, and allows one-hand closing without putting fingers in the blade path.
Key features:
- Dual springs for even pressure on both sides
- Steel crossbar for durability
- No handle flex required — solid feel
- Easy to operate with gloves
- Compatible with any blade deployment method (thumb stud, flipper, etc.)

Performance and Feel
The DuraLock's action is smooth and intuitive. Compared to the Axis lock, it feels slightly stiffer at first but breaks in nicely with use. The locking engagement is positive with an audible click, and the knife is free of blade play. The CPM D2 steel offers excellent edge retention at this price, making the Iridium a strong competitor to Benchmade's Bugout and Bailout models, which typically cost $150+.
DuraLock vs. Axis Lock
The fundamental operating principles are identical, but there are subtle differences:
- DuraLock's crossbar is slightly thicker for robustness
- Spring tension is a touch stronger on the DuraLock (some prefer this security, others find it stiff)
- Kershaw's version has a larger thumb ramp for easier operation
- Warranty terms may differ (Kershaw lifetime vs Benchmade's LifeSharp)
Maintenance Considerations
Like all crossbar locks, the DuraLock requires occasional cleaning of the pivot area and spring track. Dust, grit, or pocket lint can accumulate and affect smoothness. Disassembly is straightforward with typical Torx drivers. Oiling the springs lightly keeps the action smooth.
The Kershaw Iridium DuraLock is a legitimate competitor to the Benchmade Axis lock. At $120-140, it delivers a premium crossbar lock, excellent blade steel, and Kershaw's legendary build quality. For EDC users who want ambidextrous, one-hand operation without paying Benchmade premiums, the Iridium is a compelling option. The stiffer initial action is the only minor criticism; otherwise, this is one of Kershaw's strongest recent releases.
