OLFA 9mm Ultra-Sharp Black Snap-Off Blades (ABB-50B) - 50 Blades

A YouTube video brought these blades to my attention. The YouTuber claimed that they are very sharp (as usual) but they are also very rigid. They do bend or flex like other replaceable blades and he is right. I ran some test cuts when they arrived and they work great. No bending or flexing especially in tight corners.

These replacement blades are fantastic, better than the blade that came with the OLFA knife. Super sharp.

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!

They’re extremely sharp blades.

Superb snap off cutting blades! My go to blades for installing wallpaper and getting clean cuts every time. Perfect fit in the 8mm olfa knife. Great cake and great price!

Super buenos donde dejas corte te conecta sin residuos

not what I wanted ,but no problum to return

So easy to change out. Love these.

We go through a ton of these at my sign shop. These are consistently sharper and more durable than the silver hardware store blades. They snap where they are supposed to and hold an edge longer. Would reccomend

Product as described

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.

Sharp. Very sharp. Good deal.

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.
