You have one year to sell as many as you can before the Chinese copy it and sell them for 99 cents each. Good luck.

I came up with an idea for a wrench that is legitimately useful. I searched youtube and tool catalogs and did not find one like it.

What you need to do is do a patent search, and you can do that online. It may be that there is a similar design out there, but has not been put to market for whatever reason.
