I haven't found that, but understand that my cutting is pretty limited in the kind stuff I cut. I mostly cut narrow (not thin) stuff... zip ties, plant stems, packing straps, that kind of thing. Once the edge has made its cut, the task is usually done. Some people make very long or deep cuts into very wide materials. They have to draw their blade down through several inches of whatever it is. I can see that might make a difference in how a chisel ground, or even single bevel V-ground, blade works.
