Cutting edge is a term used to describe the creations of the small number of persons or groups who are at the frontier of progress in a field, especially science. For instance, cutting edge technology refers to technology that is the most advanced and most original technology available at the time.

Cutting edge is very similar to the term avant-garde, which has a similar meaning in the area of art and culture.

The term cutting edge can be considered a cliche due to its overuse, particularly in marketing material.
