Designed by Ken Onion with his signature curved handle ergonomics, the Blur fits the hand naturally for extended cutting tasks. The standard model uses Sandvik 14C28N stainless steel, a Swedish alloy that balances edge retention with ease of sharpening — a practical trade-off for a knife that gets used daily rather than displayed.
SpeedSafe assisted opening deploys the 3. 4-inch blade with one hand, and the Trac-Tec textured grip inserts on the anodized aluminum handle provide purchase even in wet conditions.
Made in Kershaw's Tualatin, Oregon facility, the Blur carries a limited lifetime warranty with factory sharpening service — send any Kershaw knife back and it returns with a factory edge at no charge. At around $70, the Blur costs less per year than a cup of coffee over even a conservative five-year lifespan.
Most owners report carrying the same Blur far longer than that. The knife has earned its place in the rotation of professionals and enthusiasts who measure a tool by how many times they reach for it.
