Rotary ergo cutters and blades are used by quilters to cut fabric comfortably. Our rotary cutters feature a truly ergonomic design that reduces pain and fatigue in your hands, arms, and shoulders caused by repeated cutting. The circular blades rotate, allowing the user to easily cut different shapes. Rotary cutters are available in right-handed and left-handed models with blade sizes including 28mm, 45mm, and 60mm. The blades are extra sharp and designed to last for extended use, but if you need a new one, we also offer replacement blades. They’re available in each size in packs ranging from one to 50 blades. Shop Martelli to find all the best tools to express your creativity through sewing, quilting, and embroidery.
