25mm Extra Heavy-Duty Ultra-Sharp Black Snap Off Replacement Blades, 5 Blades (35 segments) HBB-5B - Snap-Off Utility Knife Replacement Blades, Fits most 25mm Utility Knives

Very sharp, excellent blades a definitely must buy if you have an olfa knife that takes 25 mm size of blade.

Olfa makes quality blades that are super heavy duty, razor sharp and really cost just a little more than the competition. I but a whole pack and I am still on my first blade, I have yet to snap off a single blade. This knife gets used almost daily multiple times a day for opening boxes (primary use) to striping wires to anything else you need a blade for in the shop. It performs extremely well.

Very nice sturdy and sharp breakaway blades that fit in a blade carrier my friend, printed for me on a 3-D printer

These blades are very useful and they are good for cutting down cardboard boxes

Very sharp, holds edge well too.

THey're well packaged and come with a carrying case. You can't beat OLFA quality or sharpness!

Ripping sharp and corrode far slower than other options

Excelente calidad.

Work as they should

Olfa cutters have always been the best in the category of Cutters. Plus the variety of types available is commendable. we can always find one for all applications. The H-1 models is strong and lasting. Only issue - the blades are difficult to get easily. I guess not many people buy such heavy duty cutters.

Japanese blades are by far the sharpest
