OLFA9mm Snap Off Replacement Blades, 50 Blades (650 Segments) ABB-50B - Ultra-Sharp Black Utility Knife Replacement Blades, Fits most 9mm Utility Knives

A great step up from the regular blades that are just silver. Each one lasts longer and are less flimsy, clips off into olfa container cleanly and safely. Container easy to transport.

The box design - jeezus it’s great. It is what all container designs should be. This is Japanese design exemplifies. The satisfying way the box closes is so good and so simple.Oh and the blades are awesome course.

What can I say? I have used Olfa blades for over 20 years and they have never failed me. I have occasionally purchased other brands; however, they never held up to the abuse I regularly dish out. Originally, I used them to hang commercial vinyl wall paper & residential wallpaper. They cut cleanly and last. More recently, I use them to cut everything from gift wrapping to cardboard to make arts & crafts for kids. Works well in all the situations. Definitely recommend. All the best.

very good xacto blades for cutting and shaping styrene , the case will last a long time !

In the car audio/fabrication industry an Olfa blade is the ONLY blade to go with. I have many Olfa Silver pocket blades and use them for almost everything. But these blades really shine when tinting windows, wrapping speaker boxes in carpet, wrapping trim panels in vinyl and car audio installs. That’s why I get the 50pack of replacement blades. For one the price is right, they are highly durable and work better than any other blade on the market. A must have for anyone’s shop or garage.

I use these for window tinting. They are really sharp, better than hardware store carbon blades but they're so much more expensive than the stainless blades, and I snap a fresh piece for every top edge so they go quick but they're good

These ABB blades are uber sharp. I highly recommend them. They are also long lasting in my opinion. My only caution is to be careful using them as you can cut yourself severely with these blades if you're careless.

Easy & sharp. Fast & sharp. Quick & sharp. Do not sleep in the same room as these blades because they are, well, sharp eh?
