Kershaw Blur 1670BLK Overview

The Kershaw Blur 1670BLK Pocketknife is a legendary Ken Onion design that defines the “tactical workhorse” category. Moreover, the 3.4-inch recurve blade is precision-forged from Sandvik 14C28N stainless steel, providing exceptional slicing performance and corrosion resistance. Furthermore, the blade is protected by a durable Black Cerakote finish (on current production models), a ceramic-based coating that offers superior abrasion resistance and a non-reflective matte look compared to standard paints.

Mechanism and Reliability

The patented SpeedSafe® assisted opening system allows for lightning-fast, one-handed deployment using the large, angled ambidextrous thumb studs. In addition to its rapid action, the Blur utilizes a secure Inset Liner Lock—a stainless steel strip riveted inside the handle—to keep the blade safely locked without increasing the overall handle thickness. Because of this smart design and the lightweight aluminum chassis, the Blur weighs in at just 3.9 ounces, making it a substantial yet comfortable carry for heavy-duty users. If you love the Blur platform but are looking for a premium steel upgrade, we highly recommend checking out the Kershaw Blur S30V for extended edge retention.

Handle Design and Ergonomics

Furthermore, the distinct recurve drop point blade excels at multitasking, offering a slight “S” curve that pulls material into the edge for aggressive cutting of rope and boxes, while the tip remains strong for piercing. Additionally, the handle is machined from 6061-T6 anodized aluminum and features Kershaw’s signature Trac-Tec inserts—textured, rubberized grip tape that provides a secure, non-slip hold even in wet or muddy conditions. Consequently, the reversible pocketclip supports versatile tip-up or tip-down carry, ensuring the knife is always positioned exactly where you need it. You can find full technical details on the official Kershaw Blur Black product page.

Practical Applications and Everyday Carry Uses

  • Heavy Duty Work: The recurve blade shape is specifically designed for pull-cuts through tough materials like webbing, hose, and rope.

  • All-Weather Grip: The Trac-Tec inserts ensure the knife stays in your hand during rain, snow, or when wearing gloves.

  • Tactical Utility: The non-reflective Cerakote finish and fast deployment make it a favorite among first responders.

  • General EDC: Handling everything from breaking down heavy cardboard to food prep with the corrosion-resistant 14C28N steel.
