The term "cutting edge" primarily refers to a sharp, functional edge of tools or instruments, crucial in fields such as metallurgy, carpentry, and garment design. While the Norwegian jazz band Cutting Edge (1981–1986, 2002) employed the phrase metaphorically to describe their innovative blend of jazz and rock, the concept itself has been examined in practical and technical contexts.
Authors like Edwin W. Foster discussed the angle and function of sharp edges in tools, while Günther F. Hertzer analyzed their use in garment construction. These diverse viewpoints underscore the term’s dual nature—as both a physical characteristic of tools and a metaphor for innovation—connecting artistry and utility across various disciplines.
