If a tool is no longer being made or used, then the word we call it by would also be out of use, in which case none of us are likely to have ever heard of it. Of course nobody can think of any tools that are no longer around. Take belaying pins for example. Eventually people might forget what a belaying pin is as they were used on old sailboats, but when that happens the fact that people don't know about belaying pins doesn't mean belaying pins never existed.
This guy seems to believe that he know's about every single tool ever invented, which is preposterous. Anybody who says they know all about everything, including things they've never heard of or seen before, is a few french fries short of a full meal deal.
