The RB45H 45 mm replacement blades are designed for OFLA rotary cutters used for quilting, sewing and general crafts. Now, OLFA offers 2x more cuts per blade while cutting fabric before dulling. That's 1500 yards versus 750 yards (internal testing). And why? The OLFA proprietary Tungsten Steel metal chemistry features an innovative heat treatment process to create exceptional durability. And the OLFA proprietary sharpening process continues to be the industry benchmark for high-performance cutting edges. The RB45H is compatible with all OLFA 45 mm cutter handles.
