Professional Cutting Blades

The Olfa HB-5B pack supplies five snap-off utility blades built from carbon steel for tradespeople and serious DIY users who need reliable edges on site. Each blade measures 25 mm wide and delivers seven usable segments per strip for extended cutting life.

Consistent Performance

At 0.03 in thick the steel resists flex while scoring nylon, plastics and similar materials without excessive force. The snap-off design keeps the tip sharp through repeated breaks so cutting effort stays low and hand fatigue is reduced during long sessions.

Direct Replacement

These strips suit any 25 mm snap-off knife that accepts standard segment blades, letting you refresh a dull edge in seconds. The five-blade pack covers high-volume work but buyers needing hooked tips or specialised coatings should look elsewhere.

Questions about this item

How do I install the Olfa HB-5B snap-off blade and what step do users often miss?

Insert the blade into a compatible 25 mm utility knife until it locks, then extend the first segment fully; the step often missed is confirming the blade seats completely in the holder so it cannot shift during cutting.

What maintenance or replacement will the Olfa HB-5B blades need later?

Each blade provides seven snap-off segments; when a segment dulls, snap it off to expose a fresh edge, and replace the entire blade once all seven segments are used.

What limit appears first during sustained cutting with the Olfa HB-5B blades?

The 0.03 in thick carbon steel edge dulls before the blade body fails, so cutting performance drops once the current segment wears down, requiring a snap-off to continue.
