"Fluted" forks goes back in the day when "drillium" was the way to save weight. People would drill holes in their forks to save weight, making each fork blade resemble (and even sound like, at appropriate speeds and wind angles) a flute.

Unfortunately, the whole experiment with fluted forks came to a screeching halt after several catastrophic failures, and we now also now the whole endeavor was counterproductive due to the poor aerodynamics.
