The story begins with how cutting tools evolved from simple paleolithic stone edges to the knives, axes and other basic metal cuttings tools via the copper, bronze, and iron age. From there we look at the discoveries of metallurgy during the industrial era, the rise of steel, and the evolution of machine tools. We explore the advancements of the tooling mills, lathes and shapers used as cutting tool materials moved from high-speed steel to carbides, and other exotic cutting materials.
