chaser (plural chasers)

1. Someone who chases (decorates) metal; a person who decorates metal by engraving or embossing. [from 18th c.]
   • 1863, Virginia Penny, The Employments of Women: A Cyclopaedia of Woman's Work, page 100:

     "Mr B., heraldic chaser, says there are several processes in making heraldy plates, sketching, engraving, embossing, chasing and burnishing."

     "H. & C., manufacturers of cloth and gilt buttons, say it requires some weeks to learn to chase the gilt buttons, which are done with small metal tools and a hammer. Chasers are paid by the peice, working ten hours a day, and some can earn $1 a day."

   • 1971, George Bernard Hughes, Living Crafts, page 36:

     "Flat chasing in sunken or low relief is a technique by which the ornament is formed by beating down the ground from the front. This is done in essentially the same manner as repoussé work, where the ornament appears in high relief, but the design is punched from the face of the silver plate. ... Sometimes, instead of applying a freehand design, the chaser covers the greased suface with a paper pattern in which the design is pricked with pins."

   • 1972, Richard Came, Silver, page 7:

     "Chasing in general can be distinguised from engraving, in that the design can be seen on the reverse or inside of the pieces. Having outlined the pattern on the surface, the chaser cuts and at the same time slightly depresses the surface. A light hammer can be used in this process also."

2. A tool used for cleaning out screw threads, either as an integral part of a tap or die to remove waste material produced by the cutting tool, or as a separate tool to repair damaged threads. [from 19th c.]

   • 1994, Francis T. Farago, Mark A. Curtis, Handbook of Dimensional Measurement, page 467:
