Quick answer: “Cutting Edge” means at the most advanced or innovative stage of development.
Cutting edge — at the most advanced or innovative stage of development; representing the latest and most up-to-date technology, ideas, or methods.
Origin & History
The phrase draws on the literal image of a blade. The "cutting edge" is the sharpest and most forward part of a blade — the part that does the actual work. A well-maintained cutting edge is precise, efficient, and superior. In the 19th century, engineers and craftsmen used the term literally; by the early 20th century, the military used "at the cutting edge" to describe the leading-edge of combat or technology. From there it entered civilian language to describe any field's forefront.
Today "cutting edge" is one of the most common adjectives in technology, science, and business writing. It has partly lost its metaphorical freshness through overuse, but remains a clear and understood term for describing the very latest in any field. When used as an adjective before a noun it is hyphenated: cutting-edge. Idioms like this are the kind of expression documented in general reference works such as the Cambridge Dictionary, which record how figurative meanings develop in everyday English.
