In making the hammer a piece of ¾-inch square, soft steel is used. It is upset on one end to get the stock large enough for the bottom of the hammer. The bar is then drawn out on the horn as shown at [Figure 43]. The top part is formed as shown at [Figure 44]. Lines are chased on the front of hammer as shown in the drawing; this can be done after it is formed. If the lines are to be very deep it should be done while the piece is straight and heated.

There is ample room for design in the making of door knockers, both for outside and inside doors of dwellings. Knocker plates for doors on the inside of dwellings can be elaborated by a combination of repousse, chasing and perforated decoration which give a variety of light and shadow. Perforated plates can be backed up with colored leather or cloth which gives a very pleasing contrast to the metal.
