Compared to the standard LB blades, the LBB black blades increased the hardness of the steel, reduced the sharpening angle and increased the sharpening width.
As a result of these changes, ExcelBlack's initial cutting capacity was 25% higher than the standard (silver) OLFA blades, and compared to other manufacturers' blades, it was nearly twice as high.
This makes LBB blades a great choice for professionals and anyone who needs to achieve a perfect, smooth cutting edge. Ideal for cutting soft materials such as cardboard, rubber, polystyrene, cork, leather, paper, etc.
