Elmer's X-ACTO Z-Series No.11 Blades

The Z-Series is X-ACTO's sharpest, most durable blade ever! When creating this new blade, the goal was to design, develop, and manufacture a number 11 blade that is absolutely "best in class".

The gold hue on the cutting edge is a zirconium nitride coating applied at the atomic level after blades are atomically sharpened. The result is the sharpest blade in the industry.
