Spare Blades - Normal Knife

Spare blades for a standard utility knife. They matter more than their price suggests, because the alternative to a fresh blade is somebody pressing harder on a blunt one - and that, rather than sharpness, is what causes most knife injuries on a site or in a store. A snap-off blade gives several fresh edges before it is spent, and a spare pack means the whole blade gets changed when those run out instead of the knife being used dull for another week. Used across cardboard and packaging, plastic sheet and membrane, insulation, carpet and vinyl, gypsum board, rope and strapping. Snap the used tip off with pliers into a bin, not with fingers, and never leave loose blades in a pocket or a drawer.
