Lost history, confused terminology - not the only place it happens*. Walk into well-equipped garages and ask the owners what water pump pliers are, and how they're used; even a lot of people old enough to know better won't know what you're talking about.
*For a somewhat indirect example, my wife has gotten tired of me rising from my chair and ranting every time a newspaper story talks about the civil rights movement as if the Rev. Dr. Martin Luther King started it his own self - ignoring 150 years of history that preceded King, and, in particular, the years of work by people, some remembered in the histories but some not - during and after World War II that he built on. This is not to belittle King - he was one of the heroes of the civil rights movement - but he was neither the first nor the only one.
