To bend silverware, take a spoon or fork between your two hands. Put your thumb and pointer finger on either side of the bend that is already there. Slowly and carefully bend the spoon or fork until it is the shape you want.

To bend silverware for jewelry and other crafts, you can use a wooden dowel the size you want your curl to be and a rubber mallet. Place the utensil against the dowel and slowly pound it flush to the dowel's surface.
