Made from high carbon tool steel (SK-2) and sharper than most other Snap-Off blades in the world, these OLFA® Snap-Off blades have a unique 30° angle. The idea behind the acute angle is to get the sharpest point of the blade onto the surface to be cut, when cutting from a typical height on a table. The blade is 0.38mm thick and has 7 snap segments. Packed in boxes of 10.
