I used to order the blades all the time online & they worked really good. Then the last 10 packs I ordered were terrible. They wouldn't cut anything. I opened up every pack & tried each & every blade. They were all the same so I haven't bought any of them since. I must of got a bad batch or something but was afraid to try them again. We just got a new Harbor Freight in our area so I want to go check it out sometime for some of the other goodies.
