OLFA HBB-20B 25mm Black Snap Blades, 20-Pack

The OLFA HBB-20B 25mm Ultra-Sharp Black Snap Blades are designed for demanding cutting tasks where precision and durability are critical. Manufactured from premium Japanese carbon tool steel, these extra-heavy-duty blades use a multi-step dual-honing process that produces an edge approximately 25% sharper than standard silver snap blades. The result is a cleaner, more controlled cut when working with dense or abrasive materials on construction sites, in workshops, or during renovation work.

Each 25mm blade measures nearly one inch wide, providing increased leverage and strength compared to smaller utility blades. This wider profile allows users to apply more cutting pressure with better control, making these blades suitable for heavy materials such as cement board, roofing shingles, thick corrugated cardboard, and flooring materials. The snap-off design features seven cutting segments per blade, allowing users to quickly expose a fresh edge when the current section becomes dull. Deep, straight notches ensure clean and predictable snapping, reducing downtime and maintaining consistent cutting performance throughout the job.
