Review on POWERTEC 13380 Bi-Metal Blade - 0.025 Inch by Eric Temple

I bought 2 of these. The first one worked fine until it broke. It broke at the weld. When I balled it up to throw in the trash, it tore elsewhere. Most of the blade was flexible, but that part just broke in half when I folded it. I put the second one in its place. It has a material flaw of sorts as there is a patch that is wider than the rest of the blade. It trembles no matter what you do. I had to unscrew the thrust bearing to keep it from hitting that spot. Cuts well but I don't think this one will last very long. Olson blades are much better than these and cost a little more.
