Slice 10535 Chisel Blades, Narrow Double-Sided, Zirconium Oxide Ceramic, Pack of 4

These safer chisel blades feature Slice's signature finger-friendly edge, which scrapes effectively but is safe to the touch. Made of 100% zirconium oxide, they are non-conductive, non-magnetic, chemically inert, and will never rust. The advanced ceramic blades hold their edge up to 11 times longer than comparable metal blades, and being double-sided, each blade lasts up to 22 times longer than a single-edge metal chisel. Extra narrow for precision, they are ideal for artists, laboratories, electronics manufacturers, and more. Compatible with Slice craft handles and replaceable-blade scalpel, each package contains four blades.
