Product Description
The Kershaw Blur Navy Blue (1670NBMAG) brings a refined, high-end look to one of the most trusted tactical folders ever made. This USA-made classic, designed by Ken Onion, has been upgraded with the industry’s most advanced "super steel": CPM MagnaCut. This revolutionary American-made alloy offers a nearly impossible combination of extreme toughness, world-class edge retention, and a level of corrosion resistance that makes it virtually maintenance-free.
The 3.4-inch drop point blade features the signature Blur recurve, engineered to pull material into the edge for superior slicing and high-leverage pull-cuts. The rugged stonewashed finish expertly hides use scratches and daily wear. The handle is precision-machined from Navy Blue anodized 6061-T6 aluminum—a lightweight "aircraft-grade" material known for its extreme durability. To ensure a "locked-in" grip in any weather, the handle is outfitted with high-traction black Trac-Tec inserts. Equipped with SpeedSafe® assisted opening, the 1670NBMAG deploys with a lightning-fast flick of the thumb stud, making it a reliable partner for first responders, outdoor enthusiasts, and EDC collectors alike.
