X-ACTO Z Series #1 Knife with Cap
The X-ACTO Z-Series is our Sharpest, Most Durable Precision Knife Ever. X-ACTO’s #1 precision knife is manufactured with a carbon steel blade for a reliable cut every time. The blade was designed to be the absolute "best in class" #11 blade. The gold hue coating is zirconium nitride, which is applied at the atomic level after blades are sharpened. The blade is then re-sharpened to provide our longest lasting, durable, sharp blade that is truly best in class.
