Olfa 25mm Ultra-Sharp Black Snap-Off Blades (HBB-20B) – 20-Pack

25% Sharper. Double-Honed Precision. The Ultimate Edge for Extra Heavy-Duty Cutting.

The Olfa HBB-20B isn't your standard replacement blade; it is a premium upgrade for your most demanding tools. These Excel Black™ blades are manufactured from high-quality carbon tool steel and undergo a rigorous double-honing process. The result is an edge that is 25% sharper than Olfa’s standard silver blades, allowing you to slice through dense materials with significantly less effort and physical strain.

Designed specifically for extra heavy-duty 25mm knives, these blades provide the rigidity needed to tackle plywood, rubber matting, roofing shingles, and thick gaskets. With 140 sharp cutting segments per pack, the HBB-20B ensures your crew has the supply they need to keep the job moving at peak efficiency.

Key Features & Professional Benefits:

• Double-Honed Excel Black™ Edge: Specialized sharpening technology creates an ultra-fine edge for superior initial sharpness and effortless cutting through tough materials.
• Premium Japanese Carbon Steel: Engineered for maximum durability and edge retention, ensuring each segment stays sharper for longer than budget alternatives.
• Extra Heavy-Duty 25mm Width: The 1-inch blade width provides the structural stability required for high-torque applications where thinner blades would flex or wander.
• 7 Cutting Points Per Blade: Each blade features 7 deep-etched snap segments; a quick snap provides a brand-new, razor-sharp edge in seconds.
• 20-Pack Bulk Case: Provides a total of 140 sharp edges, offering the best cost-per-cut value for industrial shops and high-volume jobsites.
• Universal Compatibility: Designed to fit all Olfa 25mm knives, including the H-1, XH-1, and XH-AL, as well as most other 25mm utility knives.
• Safety Storage Case: Comes in a durable plastic case that protects the premium edges from damage and serves as a safe dispenser on the jobsite.
