Sometimes a bracelet bender isn't enough. A much more expensive, but very useful option is Nex Synclastic forming pliers 3/8" These pliers will form synclastic shapes like bracelets, hoop earrings and any other form that requires a concave surface. They are very easy to use. They come in three sizes 3/8", 1/2" and 3/4". The 3/8" will form a deep synclastic form with tight radiuses. Can be used with copper, silver, gold, brass, even stainless is possible. Aluminum works fine as well. Metal can be annealed or not.
