Se denomina cincel, palabra proveniente del Latín scindere, a una herramienta manual diseñada para cortar, ranurar o desbastar material en frío mediante el golpe con un martillo adecuado. El filo de corte se puede deteriorar con facilidad, por lo que es necesario un reafilado. El extremo puede ser plano, dentado o de toro.

A chisel is a tool with a characteristically shaped cutting edge (such that wood chisels have lent part of their name to a particular grind) of blade on its end, for carving or cutting a hard material such as wood, stone, or metal by hand, struck with a mallet, or mechanical power. The handle and blade of some types of chisel are made of metal or of wood with a sharp edge in it. Chisel use involves forcing the blade into some material to cut it. The driving force may be applied by pushing by hand, or by using a mallet or hammer. In industrial use, a hydraulic ram or falling weight ('trip hammer') drives a chisel into the material. A gouge, one type of chisel, serves - particularly in woodworking, woodturning and sculpture - to carve small pieces from the material. Gouges most frequently produce concave surfaces. A gouge typically has a 'U'-shaped cross-section.
