I always thought that modern drawbars would be a killer application for a "Rolamite".

"WTF is a..."

The Rolamite is a low-friction linear pulley arrangement.  It was heavily promoted in the old Edmund Scientific catalog as a new "Simple Machine", but I've never heard of many applications for it.  Apparently it's used as a crash detector for airbags.

A Rolamite might also be great for a sliding guitar pickup.
