Kershaw Interval Fixed Blade Knife, 3.5 inch Blade Made with PA-66 Nylon, Blunt Edge with Sharp Point, Project Atom

The Kershaw Interval Fixed Blade Knife features a 3.5-inch blade built for utility and field work. This fixed blade design from Kershaw's Project Atom initiative delivers a blunt edge with a sharp point—a purposeful geometry that balances edge retention for slicing tasks with point control for detailed work. The PA-66 nylon construction provides a lightweight, durable handle that resists moisture and impacts in demanding environments.

Fixed blade knives excel where folders lack durability and folding mechanisms cannot be tolerated. The Interval's 3.5-inch blade length sits in the practical middle ground—long enough for food prep, material processing, and general utility cutting, yet compact enough for everyday carry and tactical kit integration. PA-66 nylon handles offer superior reliability in wet conditions compared to natural materials, and they don't degrade in extreme temperature swings. The blunt edge paired with a sharp point is intentional: the blunt design reduces accidental cuts during handling or in close quarters, while the point retains the piercing capability needed for precise tasks.

This knife serves users who prioritize field reliability over carrying comfort—search and rescue personnel, outdoor enthusiasts, tactical operators, and professionals who depend on consistent blade geometry. Fixed blade knives eliminate the failure modes inherent to folder mechanisms, making the Interval a choice for harsh environments where blade lock failure is not an option. The blunt-edge-with-sharp-point design reflects Kershaw's engineering toward controlled cutting rather than aggressive slicing, making it suitable for users who value precision and safety in high-stress situations.
