If it is desirable to sink the nail head below the surface,a nail punch, or set, is used. This is always necessarywhen the suiface is to be planed after the nailing. 19. The Mallet. The mallet might be described as ahammer with a wooden head, and is used whenever wewish to dehver a blow which shall beless concentrated than that of the. Hammer. It is used in certain kindsof heavy chiseling, such as houseframing, and gives a blow which does not shatter thetool handle as a hammer would. The use of the mallet is well illustrated by the mak-ing of a mortise-and-tenon joint, the chisel and malletbeing used to cut the opening known as the mortise, asshown in Fig. 46. 20. Screw-Driver. The screw-driver is perhaps themost common of household tools, and is probably abusedmore than any other. The handle is usually flattenedso that the hand may grip it more tightly, but occasion-ally a round or fluted handle is seen. 34 ELEMENTARY WOODWORKING Patent spiral screw-drivers have come into use inrecent years, but where considerable force is requiredthe brace and screw-driver bit are more effective.
