I have a relative who used to be a manager at a Jiffy Lube. A year or two ago I asked him to save a bunch of used wiper blades and told him the reason behind it. Couple weeks later I had dozens of blade inserts. He even went through the trouble of stripping them down for me and giving me the bare metal. About half of them were too wide, stiff, or too heavy, but I got a enough good ones to make LOTS of motor hooks. I use a pair of Klein 2000 series side cutting pliers cut them to the right length. Cuts through 'em like butter.
