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

I’ve been using the OLFA 9mm Snap-Off Replacement Blades for wrapping and window tinting, and they’ve quickly become a must-have in my toolkit. These blades are incredibly sharp and durable, making precision cuts effortless. The snap-off design means I always have a fresh edge ready to go, which is especially important when working on detailed vinyl wrap jobs or tint installations where clean lines are everything. What really stands out is how smoothly they cut—no tearing, dragging, or missed edges. They fit perfectly in my OLFA utility knife, and I’ve noticed they stay sharper longer than other brands I’ve tried. If you’re in the business of vinyl wrapping, automotive tint, or any kind of detail work, these blades are 100% worth it. Highly recommended for professionals and serious DIYers alike!

So easy to change out. Love these.

Olfa blades are unmatched

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.

Real bargain compared to buying the handle packs. Easy to replace and I like the quantity.

They might cost more, but there’s no substitute for the quality of the Olfa blades, stay sharp longer and cut great. I use these for paint protection film mostly, and vinyl.

not what I wanted ,but no problum to return

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.

I thought it might be a bit of a gimmick but I gave these blades a try. Compared to regular blades of this type, I can assure you these ones are not only far sharper, but they maintain their edge far longer. The combination of both of these features made them my new go to, and I have picked them up in other formats as well (both 9mm and 18mm as well as the single edge ones) Best blades around. Highly, highly recommended.

Sharp. Very sharp. Good deal.

I give this all sorts of use and they are really resilient. They don't rust easily, they are super sharp and you really have to push it to break them.

Cheap, but brittle. OK for cutting paper, but on anything harder will chip. For cutting such as plastic or FR4 (PCB) strongly advise more expensive blades. Photo shows damage to end and nicks from cutting plastic.
