A secret nail for dowelling and other purposes in wood-working is shown by Fig. 459; this is useful for jointing pieces of wood together edge to edge, for which purpose the ordinary wooden dowelling peg generally, or, more frequently, a French nail or wire nail with the head taken off and a rough point made with a file, is used; wire pins thus formed will, when used at intervals along a joint, hold pieces of wood together very well, and there will be considerable difficulty in forcing two pieces apart when thus connected. The double-pointed nail can be used in cabinet work and joinery, for closely and firmly jointing floor boards and parquetry work, in putting together shelving and pieces of wood of narrow width to form the sides of boxes. For small work the nails are cut in four useful sizes—namely, 3/4 in., 1 in., 1 1/4 in., and 1 3/4 in. The nail has a projection or hammer-head as shown, by which it can be driven home into one of the pieces to be jointed, the chisel edge or point readily penetrating the material; the piece to be attached is placed against the point projecting from the wood into which the lower half of the nail has been driven and blocked down. When used in connecting hard wood, holes for the points should first be made with a bradawl.
