Slice® 10528 utility knife blades have a pointed tip for cuts that require a piercing action. As with all Slice safety blades, our 10528 blades are non-sparking, non-magnetic, chemically inert, feature no oil coating, and never rust. Our proprietary finger-friendly® edge is safe to the touch, reducing injuries and lowering costs. These blades are compatible with several Slice handles: the 10550, 10554, 10558, and 10562 utility knives; the 10591 and 10593 scrapers; and the 10585 Manual Carton Cutter.
