Kershaw Blur A/O Black Aluminum 3.4" CPM-Magnacut Blade KS1670BLKMAG

Kershaw Blur A/O MagnaCut – A Classic, Upgraded with Cutting-Edge Steel

The iconic Kershaw Blur gets a high-performance upgrade with CPM MagnaCut steel in the KS1670BLKMAG model. Designed for everyday use and demanding work, this Blur features a 3.4-inch slightly recurved drop point blade that delivers exceptional slicing and piercing capabilities. The MagnaCut blade steel offers the perfect balance of edge retention, corrosion resistance, and toughness—making it one of the most sought-after steels in the knife world today.

The black anodized 6061-T6 aluminum handle—the same material often used in aerospace applications—ensures lightweight strength, while the Trac-Tec inserts provide a secure, grippy feel even in wet conditions. Kershaw’s SpeedSafe® assisted opening mechanism makes one-handed deployment fast and easy using the dual thumb studs. A reversible pocket clip, inset liner lock, and lanyard hole round out this battle-tested design. Proudly made in the USA, the Blur MagnaCut brings elite performance to a proven platform.
