The Olfa Heavy Duty Excel Black Blades have been specially designed for use with the Olfa Heavy Duty X Design Snap Knife to enable you to easily cut wallpaper for the perfect finish. These heavy duty blades are long lasting and can easily be snapped off when no longer required.
They are not only ideal for cutting wallpaper but also vinyl and cardboard too. Excel Black Ultra Sharp Blades are manufactured using a special double honing process. Sharpened over a wider angle, they are much, much sharper than other blades on the market.
