Olfa rotary cutter blades are blades used in Olfa brand rotary cutters, which are commonly used in sewing and quilting. These blades come in various sizes, such as 18mm, 28mm, 45mm, and 60mm, to accommodate different cutting needs. The rotary cutter blades are made of high-quality tungsten carbide steel or stainless steel, which allows them to remain sharp for a long time and cut through multiple layers of fabric with ease.

Olfa rotary cutter blades are available in different styles, including straight blades, wave blades, pinking blades, and more, for a variety of cutting needs. Straight blades are the most common and are used for straight cuts, while wave blades are used for decorative edges. Pinking blades are used to create a zigzag edge that helps prevent fraying.

It's important to replace rotary cutter blades regularly to ensure optimal performance and safety, as dull blades can cause jagged edges and potentially harm the user.
