Our "Door Knob" tamper is quite elegant while being very practical for giving you a superior tamp. The knob itself is 48 millimeters (almost 2 inches) in diameter, which centers directly over the tamper surface. This allows you to put the center of your palm on the knob, and put the tamping pressure directly over the puck. It gives you a great and efficient tamp.
In addition to being very practical and allowing you to put all of your tamping force directly over the coffee puck, itís a beautiful piece. While as we had said that the knobís diameter is about 2 inches, the height of the entire piece is only 3 inches. This makes the tamper look compact and symmetrical Ė not at all like most tampers.
