Rolling knives

A rotary cutter lets you cut fabrics quickly, cleanly, and precisely. It’s ideal for sewing projects, patchwork, quilting, and other creative projects where straight lines or multiple layers of fabric are important. When used with a cutting mat and a ruler, you can work neatly and with precision, without the fabric shifting, as can happen when cutting with regular scissors.

In this collection, you'll find Prym rotary cutters and replacement blades in various sizes. A 28-mm rotary cutter is handy for small shapes, curves, and detailed work. A 45-mm rotary cutter is a great all-around size for straight lines, strips, larger pattern pieces, and patchwork blocks.

A sharp blade makes a big difference when cutting fabrics. Do you notice that your rotary cutter is fraying, skipping, or requiring more pressure? Then it’s time to replace the blade. With replacement blades, you can keep your rotary cutter in good condition and continue to work safely and accurately.

What do you use a utility knife for?

A rotary cutter is used to neatly cut fabric, patchwork pieces, quilting fabrics, and pattern pieces to size. The round blade rolls over the fabric and cuts precisely along a ruler. This makes a rotary cutter especially useful for straight strips, squares, triangles, and repeating shapes.

28 mm or 45 mm utility knife?

The size of the rotary cutter you choose depends on your project. A 28 mm rotary cutter is suitable for smaller shapes, curves, and precise work. A 45 mm rotary cutter is the most commonly used size for general cutting, patchwork, quilting, and longer straight lines.
