International ClassesB26D 003/00B24C 001/00 AbstractA cutting apparatus for cutting using a pressurized jet of fluid from a high pressure fluid source includes a hand-held tool, a hose for delivering pressurized fluid to the hand-held tool from the high pressure fluid source, and a nozzle at a distal end of the hand-held tool. The nozzle has a channel capped by a jewel. The jewel has a second channel therethrough restricting the flow of fluid through the channel, thereby creating the pressurized jet of fluid. A trigger switch is located on the hand-held tool. The trigger switch activates the high pressure fluid source when depressed and deactivates the high pressure fluid source when released.Other References
