The bell-faced hammer is to be preferred to the flat-faced type, as it will not mar the wood so badly if the nail is missed, though more skill is required to use it. Upon rough work, the bell-faced hammer will sink the nail beneath the surface without bruising the wood badly. Upon inside work, the nails should be sunk beneath the surface with a nail set.
(B.) In nailing, the young workman should acquire the habit of grasping the handle of the hammer at the end, as this will give greater force to the blow. Upon light work, the hand will naturally slip a little toward the head. Nails should generally be driven in a slanting direction, as they hold better than if driven straight. When nails are driven as shown at a, Fig. 37, it is called “toenailing,” and when driven sufficiently to hold, but not driven home, as at b, they are said to be “tacked.” Nails are driven this way when they are to be pulled out again, as in stay laths, and in fastening pieces temporarily.

Set.
In forcing matched boards together, do not pound directly upon the tongue edge of the board, but upon a waste piece of the same material, as the tongue will be bruised so that the next board will not form a good joint. Care should be used that the hammer does not strike the edge of the board when the nail is driven home. To guard against this, a nail set should be used to sink the head beneath the surface, as in Fig. 38, so that the next board will come to its place without trouble. This is called “blind nailing.”
35. The hatchet (A.) is used for hewing light work, for shingling; and as a heavy hammer, though the face is rarely tempered to stand very heavy usage (Fig. 39, a).
(B.) A hand axe, or broad hatchet (Fig. 39, b), usually is a better grade of tool than the hatchet, and as it is of greater weight, is better adapted for heavy work. A hatchet or hand axe for general use should be sharpened as at c; but for hewing only, an edge like d will give the best results.
