Wide range of straight three-hole-blades (3-Hole) optimized for cutting in different materials. We coat Razor Blades to protect the blade from abrasion, to reduce friction, and increase performance and durability.
Wide variety of rounded three-hole-blades optimized for cutting in different materials. In order to reduce the risk of shears in the blade, we recommend using straight 3 hole blades, rather than rounded ones. The industrial razor blades are available in different versions in order to be better suited for different materials.
