Old rotary style desktop telephones used principally today as a discreet weapon in the home. These units have a handhold in the back which adds to superior comfort and control. It has been noted that during successful implementation of this weapon, the unit gives a plesant sounding ring upon collision with the head.
Barry came around the house looking for trouble, so I gave him a taste of the face smashing phone. He ain't comin' round here no more.
