The concept of ambidextrous scissors exists, and a patent for the design of such a scissor which involves double-edged blades and a rotating handle was granted back in 1976 (https://en.wikipedia.org/wiki/Scissors#Right-handed_and_left-handed_scissors). However, more than four decades later, ambidextrous scissors do not exist in the market. Other than the misleading promotion of particular scissors as ambidextrous when they are actually just right-handed scissors with identically shaped handles, of course.
