[Urbane Guerrilla]

All but one of the Kamov design bureau's helo designs feature counterrotating rotors on a coaxial shaft arrangement. See particularly the Ka-25 Hormone and Ka-32 Helix.

From the 1950s came a two-shaft machine that enjoyed some popularity in the States with intermeshing twin two-blade rotors that had to counter-rotate as their disc planes intersected, so they had to turn like eggbeater blades.

Even fixed-wing propeller aircraft only mostly turn clockwise. Griffin-engined Spitfires and the Zlin 526 Trener turn their props counterclockwise.
