This is a close-up of a finished Flat Die Board, a crucial component in the packaging and printing industry. This tool is made by embedding sharp steel rule blades and specialized creasing/perforating rules into a precisely cut wooden base (usually plywood).
The resulting die board is placed into a die-cutting press to quickly and accurately stamp out hundreds or thousands of pieces of material (like cardboard, corrugated board, or paperboard) into specific shapes, typically the flat templates for boxes and cartons.
