Dapping blocks, dapping sets and punches, and other shaping blocks help you create smooth curved and domed shapes with your metal. Dapping sets are often used with disks, but can be used to dome almost any metal shape. The wooden dapping sets are usually used for shaping metal clays or polymer clays rather than sheet metal. The hardwood Whaley Swage Block is designed for forming ring shanks (without marring your metal) -- click into the product details for a how-to video.
