In each of the tips of horn is a notch for the string called "the nock."

Scarcely had Johnny stepped back to nock an arrow, than the other saw him.

This is the application of the nock of the arrow to its proper place on the string.

In each of the tips of the horns is a notch for the string, called the nock.

He thought seriously for several moments, then telepathed Nock.

The first of these is for the cock feather and should be on a line perpendicular to the nock.

The “bob-tail” diminishes from the pile to the nock; the “chested” tapers from the middle to the pile.

The nock should be strong, and very carefully finished, so that no injury may be done by the string or to the string.

Care must be taken that the nocking-part of the string exactly fits or fills the nock of the arrow.

The stick with the nock appears to be the butt end of a projectile shaft.
