Open ended ratchet wrench

You might think Knowbodies is my only "get rich quick" scheme, but that would be wrong. I also devote quite some time to pondering inventions that might propel me upwards in life. For instance, recently I was wondering why nobody sells an open-ended ratchet wrench or snow tires with retractable studs. I went to Google Patents, and ended up spending the day; not only do they  have multiple versions of open-ended ratchet wrenches and retractable stud tires, they have lots of other stuff that you wouldn't even suspect existed. And illustrations galore!!! A particular pleasure is the clarity of language that is typical of inventors. In 1933, for example, the optimistic Joseph De Merolis and Alexander di Lizio, probably struggling to contain their excitement, introduced their illuminated shoe with this pithy preamble: "Our invention relates to improvements in electrically illuminated shoes, and particularly to dancing shoes." Google Patents is truly an amazing site. (and if this particular shoe is not to your liking, there are many other illuminated shoes to choose from)
