Review on 🔪 OLFA 9149 ABB-50B 9mm UltraSharp Black Snap-Off Blade, Pack of 50 by Mark Fleming

I work in a factory that uses these 9mm knives for deburring injection molded car parts. The added sharpness of these blades makes it easy to trim away excess plastic, but be aware that the blades dull fairly easily and in my experience tend to be brittle. I have found that the super sharp black blades break more easily if not cut with a straight sharp edge. For example, if you have to rake the black blades to the side in a tight spot, they will break. Other than that, it's an excellent blade, just wish you could find some ultra sharp with 30 degree angle, tell me about OLFA custom batch, our factory will appreciate steeper angle :)
