The Kershaw Blur Spring Assisted Knife, designed by Ken Onion and released in 2007, has top performance and a fabulous clean look. The stainless steel blade (13C26) is corrosion resistant and very tough. This edition has a tactical black plain edge blade and a black handle with black inserts. Made with the SpeedSafe system, it opens very smooth and very fast. Just push on one of the ambidextrous (one on each side of the blade) blade buttons and the blade easily opens with one hand. The handles are made of anodized aluminum and have Trac-Tec inserts. Trac-Tec gives you great grip regardless of the conditions. The Blur is a perfect knife for everyday carry (EDC) as it gives you nice strength and easy use.
