Kershaw KS1670BW Blur LinerLock A/O BlackWash
Meet the Kershaw Blur BlackWash, the iconic American-made folder that’s built for real work, real grit, and real everyday carry. Designed by the legendary Ken Onion, the Blur is a modern classic—tough enough for job sites, sharp enough for precision tasks, and fast enough for life on the go.
This version features Kershaw’s signature BlackWash™ finish, giving the blade a battle-worn, broken-in look right out of the box. It’s the kind of finish that hides scratches, shrugs off wear, and only looks better the more you use it. Paired with high-performance 14C28N stainless steel, the Blur delivers the perfect balance of corrosion resistance, edge retention, and slicing power—making it a trusted companion for everyday users, first responders, contractors, and serious knife enthusiasts alike.
Flip it open once, and you’ll feel the difference. Kershaw’s assisted opening system fires the blade to attention with a smooth, authoritative snap the moment your thumb touches the stud. The slightly recurved blade geometry maximizes cutting efficiency, giving you exceptional performance whether you’re tearing through rope, breaking down boxes, tackling work tasks, or slicing your next camp meal.
The handle is crafted from rugged 6061-T6 anodized aluminum, lightweight yet incredibly durable, with Trac-Tec grip inserts that lock your hand in place—even in the rain, with gloves, or on long workdays. An inset liner lock keeps everything secure, while a reversible pocket clip provides flexible, reliable carry in either tip-up or tip-down orientation.
From the construction site to your weekend pack, the Kershaw Blur BlackWash is the no-nonsense workhorse you’ll reach for again and again. Purpose-built. American-made. Ready for anything.
