There are five main parts of the bearded needle (Fig. 3.2):
1 The stem, around which the needle loop is formed.
2 The head, where the stem is turned into a hook to draw the new loop through the old loop.
3 The beard, which is the curved downwards continuation of the hook that is used to separate the trapped new loop inside from the old loop as it slides off the needle beard.
4 The eye, or groove, cut in the stem to receive the pointed tip of the beard when it is pressed, thus enclosing the new loop.
5 The shank, which may be bent for individual location in the machine or cast with others in a metal 'lead'.
