Yeah, wasn't what I was expecting when I found the patent. The other weird thing is, for a company making tools, there are sure not many tool patents...
And there is sure not much info on the company, I have seen them before only because I found an S-wrench with their name on it. Yours is the first more or less modern wrench I have seen, and the crate tool thinggy is new to me also...
If you look only at the patents, you would think they only made engines...
