There are several varieties of nail sets, of which the cup set and spur set are most common. The cup set (Fig. 163 A) has a cup-like cavity at the lower end to set over the head of the nail or brad. This style is excellent for very small brads. The spur set (Fig. 163 B) has a small point at the center of the lower end. This point is quite small, but sufficiently large to keep the set from slipping off the nail head. The spur set is better for large brads and nails. Be careful to use a set of the proper size to correspond with the brad or nail on which it is to be used. The method of using the sets is shown in Fig. 27. Frequently the head of a brad or nail may be used instead of a nail set, as shown in Fig. 28.
