OLFA 9149 ABB-50B 9mm UltraSharp Black Snap-Off Blade, 50-Pack

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.

Olfa blades are unmatched

So easy to change out. Love these.

I use knives daily in my work and I have to say that the difference from other blades is very noticeable for sharpness and durability… totally worth the money!

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!
