An auto-retractable utility knife featuring a ceramic blade for safer handling and ideal for use in the home, office or on the factory floor. The ceramic blade is both harder than steel and harder wearing, lasting up to 10 times longer than a comparative steel blade, meaning that it doesn't have to be as sharp. This is makes it perfect cutting through paper, cardboard, tape and plastic packaging. The handle features an ergonomic grip, suitable for both left and right-handed users and has a storage compartment for a spare blade.
