The Z-Series is the sharpest, most durable blade ever !
When creating these new blades, the goal was to design, develop and manufacture a number 11 blade that is absolutely the “best in the class”
The gold hue on the cutting edge is a zirconium nitride coating applied at the atomic level after the blades are atomically sharpened. The result is the sharpest blade in the industry .
