What I was thinking was, aren't door handles so much better than door knobs? Apparently, Americans really love door knobs, while we Brits tend to go for handles. The Americans are wrong. Door knobs are totally stupid: you can't get a proper purchase on them when you turn them; whereas door handles are proper levers.
Archimedes reckoned, if you gave him somewhere to stand and a big enough lever, he could move the earth. This wasn't just idle torque on Archimedes' part; levers are definitely where it's at. You certainly wouldn't catch Archimedes saying, "Give me a big enough knob, and I will move the earth".
Although it's a hell of a chat-up line.
