The key to die cutting is the die board or steel rule die.  A steel rule die is a cutting tool similar in form and function to a cookie cutter. Sharpened steel blades are bent and formed to the pattern to be cut. The blades are held in position with either high density plywood or steel braces. The die and material to be cut are placed in a press and the final shape is stamped out. 

  Conventional steel rule dies attain the highest accuracies and can represent the most intricate of forms. To maintain tight tolerances, all of the plywood is processed using laser cutting machinery. The blade thickness typically runs between .028 and .056 inches. Fold lines, scores, and perf cuts can all be made. It is also possible to partially cut through a material, such as for adhesive stickers.
