OLFA 18 mm Heavy-Duty Ultra-Sharp Black Snap-Off Blades are the solution for tough projects when you need your utility knife to hold its own. Double-honed carbon steel provides durability and a resilient sharp edge to get you through substantial projects from beginning to end.
Extreme sharpness, 25% greater than that of OLFA silver blades, will give you the upper hand against asphalt shingles, rubber, carpeting, vinyl, or other building material you need to sink your utility knife blade into to get the job done. These extra sharp blades have eight segments each, designed to snap off when you need a new blade edge. Face your remodeling or construction tasks with simplicity and durability. Available in packs of 5, 10, 50, and 100.
