I would actually agree with you there, but I suspect that wasn't your point.

A hammer is such a simple and obvious concept that it should not need to be googled. If anybody needs to do that anyway, you should not put the blame on the carpenter, but on the guy who "designed" the hammer.

On a related note, I still very much am convinced that Don Norman's Design of Everyday Things is a great read for anyone who designs APIs; types in this argument function both as affordances and force functions, which are the exact reason why a hammer is such an obvious tool.
