X-Acto's goal with the Z Series was to design, develop, and manufacture a No. 11 blade that is absolutely "best in class." They succeeded. Early consumer response has been positive, with users saying they noticed a significant improvement in sharpness, tip durability, and cutting performance, particularly in production and assembly line applications.
A Zirconium Nitride coating on the cutting edge of Z Series blades adds significant strength to the blade, particularly the tip, for long life.
These blades are seven to 10 times sharper than standard
