OLFA 45mm Scallop Rotary Blade — Stainless Steel Replacement, Single-Pack with Protective Case

OLFA 45mm Scallop Blade (SCB45-1) is a stainless steel rotary replacement blade that creates neat decorative scalloped edges on fabric, paper, and craft materials.

Designed as a single-pack refill for 45mm rotary cutters, this scallop blade delivers a precise, repeating decorative cut without sacrificing edge life. Machined from high-grade stainless steel, it balances sharpness and durability so hobbyists and professionals can trim, embellish, and finish projects with consistent results. The blade ships in a protective case for safe storage and straightforward replacement when the cutting quality begins to fade.

How does this scallop blade improve my decorative cutting?

The scallop profile cuts a uniform, rhythmic edge that gives a finished look to quilts, appliqués, and paper crafts. Because it’s a rotary blade, it glides smoothly through layers with less dragging than scissors or pinking shears. Expect cleaner scallops with fewer frays on woven and non-woven materials when used correctly.

• Scalloped tooth geometry for repeatable decorative edges
• Rotary format lets you cut long continuous curves and shapes
• Reduced fabric distortion compared with hand shears
• Protective case for safe transport and storage

Which materials can I cut with this blade?

This OLFA scallop blade is suited to a variety of craft materials: fabric, fleece, felt, paper, cardstock, and thin vinyl. It performs best on up to a few stacked layers—ideal for trimming quilt blocks or making decorative borders on cards—but is not intended for dense plastics or thick laminates.

• Works on natural and synthetic fabrics, plus craft papers
• Great for layered quilting and applique trimming
• Not recommended for heavy-duty plastics or metal
• Use a cutting mat for best results and blade longevity

Is this blade compatible with my rotary cutter?

The SCB45-1 is a 45mm diameter blade and fits most standard 45mm rotary cutters on the market. For best performance, pair it with OLFA’s 45mm Ergonomic Rotary Cutter models, though many third-party handles will accept this blade if their specifications match. Always follow your cutter’s instructions when installing replacement blades.

• 45mm size—compatible with most 45mm rotary cutters
• Recommended pairing: OLFA 45mm Ergonomic Rotaries for optimal fit
• Include blade shield and follow installation safety steps
• One blade per refill pack in a protective carrier case

How long will the blade stay sharp and how do I maintain it?

Longevity depends on materials cut and frequency of use; cutting paper and multiple fabric layers shortens life faster than single-layer fabric trimming. Keep the blade clean, avoid cutting through pins or hard debris, and store it in its case when not installed to protect the edge. Replace the blade once scallops become uneven or require extra pressure to cut.

• High-quality stainless steel for improved edge retention
• Inspect before use; replace if chipped or dull
• Use a clean cutting mat and avoid contact with pins
• Store in the included case to preserve sharpness and safety

Who is this for: Makers, quilters, scrapbookers, costume designers, and craft teachers who want a reliable way to add decorative scalloped edges to projects will find this OLFA 45mm Scallop Blade useful. It’s ideal for anyone who already owns a compatible 45mm rotary cutter and wants to expand their finishing options with a precision blade that balances creative results and practical durability.
