Battering Ram Door-Knock Assister

Like most people, you were born with a limited number of knocks. Why waste so many of them on your co-worker's office door? With the Battering Ram Door-Knock Assister you can halve the number of knocks expended when engaging in the conventional entryway arrival announcing ritual. This device is a miniature swinging battering ram that is worn dangling from your wrist. When you hold your forearm parallel to the floor and bang in a striking motion, each strike is followed up by the swinging ram which adds a second knock. The striking face of the ram can be rubberized so as to protect the door surface, metal-plated so as to leave a mark, or with your seal carved into the metal plate so that it leaves a personalized mark.

Note: The Battering Ram Door-Knock Assister is designed to be used -only- with the side-of-the-fist banging method of knock, with forearm parallel to the floor as described above. It MAY NOT be used with the wimpy back-of-the-hand knuckle tap reputed to be common among the French (knocks such as these are why the French have the reputation they do).
