A stamping device is a tool used to imprint a design or pattern onto a surface. It consists of two components: a DIE and a dater. A DIE is a metal block with a raised design that is used to create an impression on the material being stamped. A dater is a device that prints a date or other information onto the material being stamped. Together, the DIE and dater create a stamping device that can be used to mark items with a unique design or date.
