Compared to the standard LB blades, the black LBB blades increase the hardness of the steel, reduce the sharpening angle and increase the sharpening width.
As a result of these changes, the initial cutting capacity of ExcelBlack blades turned out to be 25% higher than the standard (silver) OLFA blades , and in relation to the blades of other manufacturers it achieved a result almost twice as high.
Thanks to this, LBB blades are perfect for professionals and anyone who performs work that requires a perfect, smooth cutting edge. Perfect for cutting soft materials such as cardboard, rubber, polystyrene, cork, leather, paper etc.
The LBB-10 contains 10 blades in a plastic case.
Attention: OLFA blades are extremely sharp. Use extreme caution when cutting and changing the blade. Used blades can also be dangerous - protect them before throwing them away, for example, using containers in which new blades are delivered.
Keep OLFA knives and blades out of the reach of children!
