This Engraving Block is specially designed for handwork including engraving, jewelry making, wood carving, precision assembly and more. This flexible workholder is very stable yet easily maneuvered while you work. Self-centering jaws have tooling holes that accept a variety of pins and attachments. The top half of the vise rotates smoothly about its center. The spherical bottom sits in a socket ring so you can tilt it in any direction.
