I was at the Coolspring engine show in Pennsylvania a few weekends ago. Walking through the show I found this wrench for sale and I'm a sucker for unique wrench designs. This has got to be the most simplistic ratchet wrench I've ever seen. The end of the round bar that disappears into the ratchet head engages with notches around the outer edge. Think of it almost as a water wheel. It is about 5 inches long and the round bar is 3/16".
It is marked patent pending and I'm wondering how you would even go about trying to research a patent on something like this. Does anyone have any ideas on where to start?
