Rotary Blades 45mm
Le Summit 45mm Rotary Blades are offered in three cutting profiles to suit different project requirements. The RB-45 standard blade delivers clean straight cuts for everyday quilting and fabric work. The WB-45 wave blade creates an attractive wavy edge, while the PB-45 pinking blade produces a classic zigzag pattern that helps prevent fabric fraying.
All 45mm blades are made from high-carbon steel and precision-ground for optimal sharpness and longevity. The 45mm diameter is the most widely used rotary blade size worldwide, and Le Summit blades are compatible with 45mm rotary cutters from all major manufacturers.
