The nail-set, for sinking nail-heads below the surface, is quite important, and it is well to have a 28 large one and a fine one. The end of the set or punch must not be allowed to become rounding or it will be all the time slipping off the nail-head and punching holes in the surrounding wood. A slight conical depression in the end of the set is good. Do not use a file for a nail-set, for the end is too hard and will dent the face of the hammer-head.

Fig. 611.

When setting nails, hold the nail-set firmly against the little finger, placing the latter on the wood close to the head of the nail, as shown in Fig. 611. This will keep the set from slipping off the nail-head and damaging the work.
