Kershaw 1670BLKST Blur 3.4" Folding Knife, Partially Serrated Black DLC 14C28N Steel Blade, Black Anodized Aluminum Handle with Pocket Clip

The Kershaw Blur 3.4" folding knife combines speed, versatility, and solid American manufacturing into a everyday carry workhorse. Built around a slightly recurved blade that handles everything from slicing to piercing, this partially serrated folder is equally at home in a backpack, on a work belt, or in your pocket during a day afield. The 14C28N stainless steel blade earns its reputation for holding an edge while shrugging off corrosion—and the black DLC (Diamond-Like Carbon) coating adds both durability and a refined tactical look that resists scratching better than bare steel.

Where the Blur really shines is in the details. SpeedSafe assisted opening means one firm press on the thumbstud and the blade deploys with authority, no fumbling required. The handle is built from 6061-T6 anodized aluminum—the same material aircraft use—paired with textured Trac-Tec grip inserts that lock in your hand even when things get wet or greasy. A reversible pocket clip gives you the freedom to carry tip-up or tip-down, and there's a pre-drilled lanyard hole if you want to tether it. The locking liner keeps the blade secure under load, so you can trust it during demanding cuts.

Kershaw's commitment to Made in the USA manufacturing means this knife carries genuine domestic engineering and quality control, not just assembly. At 3.9 ounces and 7.9 inches fully open, the Blur strikes a balance—substantial enough to handle real work, compact enough to forget it's there. Whether you're a hunter sorting game, a camper processing firewood, or someone who simply carries a knife because a quality blade solves problems faster than anything else, the Blur earns its place in your rotation.

Frequently Asked Questions

Is the Blur good for hunting and field processing?

Yes. The slightly recurved blade excels at both slicing and piercing tasks, and the partially serrated edge handles fibrous material like sinew and hide. The 3.4" blade length is substantial enough for real work without becoming unwieldy, and the DLC coating resists rust if you're working in wet conditions.

Can I carry this knife tip-up and tip-down?

Absolutely. The pocket clip is reversible, so you can configure it for either tip-up or tip-down carry depending on your preference and your rig setup.

How does SpeedSafe assisted opening work?

Press the thumbstud with your thumb to overcome the spring tension, and the assisted mechanism takes over to complete the blade deployment smoothly and quickly. It's designed for one-handed operation.

What does the DLC coating do?

The black DLC (Diamond-Like Carbon) coating adds an extra layer of corrosion resistance beyond what the 14C28N stainless steel provides on its own, and it also resists scratching and scuffs better than bare steel, keeping the knife looking sharper longer.
