Featuring a ceramic blade that's safer than metal, the Slice Manual Utility Knife cuts materials effectively but resists cutting skin. And the patented finger-friendly ceramic blade lasts up to 10 times longer than a steel blade, so you don't have to replace it as often. The blade adjusts to five different positions, so you can choose the right blade depth for the job. It extends up to 1" (24 mm) long . The handle is made of durable glass-filled nylon. There's also a hole at the end if you want to attach a lanyard for added convenience. The knife can be used left- or right-handed. Slice ceramic blades are non-sparking and chemically inert, and they'll never rust. When you do need to replace the blade, the process is easy — no tools required.
