A waterjet is a tool used to cut metal, plastics, wood, rubber, marble, etc. with a (very) high-pressure stream of water. Think of a waterjet as something with about 30 times the pressure of the power washer wand at your local car wash.

The key to cutting metal and other materials with water is to keep the spray coherent. Waterjets are able to cut because the spray is channeled through a very narrow jeweled nozzle at a very high pressure to keep the spray coherent. Unlike metal cutters, a waterjet never gets dull and it cannot overheat.
