The Slice 10534 Chisel Blades combine our finger-friendly grind with exceptionally strong zirconium oxide for a stable, precise, and safe scraping edge. Perfect for detailed work, these blades are compatible with most Slice craft and scalpel handles. The blades' chemically inert, autoclave-friendly, and non-conductive properties make them an ideal choice for electronics manufacturers or lab workers. Like all Slice safety ceramics, they are safe to the touch and last up to 11 times longer than comparable metal blades.
