OLFA 25 mm HBB Ultra‑Sharp Black Snap-Off Blade – 5 Pack

The OLFA 25 mm HBB Ultra-Sharp Black Snap-Off Blade 5-pack supplies extra heavy-duty cutting power for tough materials like leather, vinyl, carpet, canvas, plastics, cardboard and heavy fabrics. These premium blades are forged from high-carbon tool steel and undergo a dual-honing process that makes them about 25% sharper than standard silver blades. 

Each blade has seven razor-sharp segments that snap off cleanly to reveal a fresh cutting edge — no sharpening needed. Deep score lines ensure a safe, easy snap whenever you need to refresh the blade. 

This blade pack fits most 25 mm utility knives and cutters. It is perfect for sewing studios, upholstery, bag making, leatherwork, DIY jobs and any project where strong, precise cuts through thick or layered materials are needed
