The machinists’ hand hammer is usually made in one of the three forms shown in [Figs. 2094], [2095] and [2096], and varies in weight from about 13⁄4 lbs. for heavy chipping to about 1⁄2 lb. for light work, the handle being about 15 inches long for the heavy, and about 10 or 12 for the light business. The round face is usually somewhat convex on its surface with its edge slightly rounded or beveled. The pane or pene a, [Fig. 2097], is usually made in European practice to stand at a right angle to the axis of the handle as shown, while in the United States it is usually made to stand parallel with the handle as in [Fig. 2096]. The face end is sometimes given taper as in [Figs. 2094] and [2095], and at others parallel as in [Figs. 2097] and [2098], or nearly so. The pene is mostly used for riveting purposes, and it is obvious that with the pene at a right angle to the handle axis as in [Fig. 2097], it will not matter whether the pene meets the work quite fair or not, especially as the pene is made slightly curved in its length, and it is easier to hold the hammer level sideways than it is to hold it so true lengthways that the pene, when forward, as in [Fig. 2096], will meet the work fair.
