The Slice Chisel Blades (Narrow, Double-Sided) are a stronger, safer option for those who use chisel blades with craft knives. These thicker-than-standard blades are made with advanced ceramics-much harder than steel-for durability and strength. At the same time, they feature our proprietary finger-friendly edge, which makes them safe to the touch. The narrow profile lets you get into tight spaces for intricate work. Each edge lasts up to 11 times longer than a comparable steel blade. When the first side wears out, simply flip the blade around for a fresh edge. Slice blades are all non-sparking, non-conductive and chemically inert. They won’t rust and they fit in a number of our craft handles to suit your needs.
