I have used Olson blades in the past with good results and have ordered these as a replacement. When I assembled it and did a test cut, I immediately noticed a thud and a jerking in the cut with each rotation of the blade. The jerk was enough to rip a piece of wood out of my hand! It felt like one tooth was longer than the rest, catching every turn. I removed the blade and measured each tooth. They were all 3/8 inch long except for five at the long end of the blade. These teeth were 11/32 inches. I came back late so I just lost the value of the blade. What worries me the most is that I think this has created an unsafe situation.
