Sinusoidal Stakes - Wave

Wave Steel Sinusoidal Stakes are precision-formed tools for anticlastic forming—the process of shaping sheet metal into opposing curves, producing graceful, flowing forms. These USA-made stakes are machined from durable steel and finished smooth for consistent contact surfaces. Commonly used in jewelry and metalsmithing for raising, shaping, and texturing curved forms.

About Anticlastic Forming

In synclastic forming, the metal curves in the same direction (like a dome). In anticlastic forming, the metal curves in opposite directions at right angles, creating saddle-like shapes. According to Michael Good’s “Anticlastic Forming” (see downloads), sinusoidal stakes are essential for controlling these complex curves and can be used with a variety of hammers depending on the stake material and desired.

Key Features

• Sinusoidal wave face supports anticlastic and synclastic forming
• Use with nylon or plastic hammers to protect the workpiece surface
• Ideal for shaping bracelets, sculptural jewelry, and hollowware

Recommended Tools & Reference

• Pair with a nylon or plastic hammer such as the Fretz 137.207 Double-Ended Inset Hammer for fine control

Usage Notes

• Use wood, nylon, or plastic mallets when working on steel stakes to prevent marring the metal surface.
• For more controlled forming, work progressively from edge to center in overlapping hammer passes.
• Anneal work-hardened metal frequently for best results.
