Precision chisels need to withstand pressure while maintaining an even scraping edge. Slice® uses 100% zirconium oxide to create exceptionally strong blades whose edges last up to 11 times longer than metal. All our blades offer finger-friendly® edges, which means they maintain effectiveness but are safe to the touch. This single-edged chisel (SPG10534) is compatible with Slice craft and scalpel handles. Sized for precision, it gives the user superior control for the kind of detailed scraping required by artists and electronics manufacturers alike. Blades come in packs of four.
