Old English cnocian, of imitative origin.

When you decide to finish an idea or plan you may say that you are going to knock it on the head, a phrase well established in English by the late 16th century.

Contestants keen to show off their skilled marksmanship would be required to shoot out the pips or spots on a playing card.

The sense ‘speak disparagingly about’ is recorded from the late 19th century in US usage.
