This steel sinusoidal stake, made in the U.S. by a master blacksmith, allows you to create synclastic and anticlastic forms; it is ideal for use with plastic or nylon forming hammers. The wave amplitude on this stake tapers from 1-1/2" to 7/8". During forming, the stake supports the metal while it is worked directly with a hammer. The different curves deliver a variety of options for the artist; by working on different areas of the stake, you can determine the shape and dimension of the metal form. See the anticlastic raising section of Metals Technic for information on how to achieve anticlastic raising with these stakes.
