These blades replace worn, bent, ragged, rusty, or missing blades on compatible utility knives. Blade shape, mounting holes, and notches must match the knife mount to ensure proper seating. Blade tips of different styles cut, pierce, or hook into material to suit different cutting tasks.
Standard, pointed tips on these blades puncture materials so their straight edge can slice through. They make more precise cuts than blunt- and round-tip blades. These blades score drywall and cut a range of materials, such as cardboard, plastics, and fabrics.
