Chisel (redirected from obstetric c's)

chisel

Cutting tool with a sharpened edge at the end of a metal blade, used (often by driving with a mallet or hammer) in dressing, shaping, or working a solid material such as wood, stone, or metal. Flint ancestors of the chisel existed by 8000 BC; the ancient Egyptians used copper and later bronze chisels to work both wood and soft stone. Chisels today are made of steel, in various sizes and degrees of hardness, depending on use.

Chisel 

(in Russian, doloto, also drill bit), a manual or machine woodworking tool for hollowing out openings, recesses, grooves, and so on. Hollow chisels with a drill inside are used in drilling and mortising machines. Chisels are also used for carving bone and other materials. Flint chisels began to be used in the Upper Paleolithic and bronze chisels, in Egypt and Mesopotamia during the third millennium B.C.; iron chisels were used in the ninth and eighth centuries B.C. In Russia steel chisels with cutting edges of standard dimensions were already being used during the tenth to 13th centuries A.D.
