Metal is out; ceramic is in! This is a four-pack of Slice blades made of 100 percent hand-sharpened zirconium oxide. Each blade features a straight edge and a rounded tip to guard against puncture accidents. As with all Slice ceramic safety blades, these blades are non-magnetic, chemically inert, non-sparking and rust-proof, making them perfect not only for craft and hobby projects but also for electronics.
Even though these knife blades are designed for use specifically in the Slice Craft Knife, they are also fully replaceable for any of your existing hobby or X-ACTO® knives!
