Hammering hardens and flattens round wire. This can be especially important when making ear wires or clasps that need to hold their shape. Always use a smooth, hardened steel surface to guarantee a clean finish. Any marks or scars on a bench block or hammer will impress on the surface of wire or sheet metal.
Create your shape from wire. Keep hammer flat to prevent marring wire. Flip over after a few taps and hammer on opposite side. Donít get carried away, if you hammer too much metal becomes brittle and breaks.
