stone burnishers can be used for bezel setting, smoothing metal, PMC work, and
many other applications. Agate is strong enough to work with metal, but soft
enough that it will not scratch or damage stones that are being set. The knife
edge blade is 1 x 0.5 x 0.25" (2.5 x 1.3 x 0.6 cm) and comes to a rounded tip.
It is set in a hardwood handle. Overall length measures 8.5" (21.5 cm). These
burnishers are made from natural agate and colors will vary.
