A pipecutter is a type of tool used by plumbers to cut pipe. Besides producing a clean cut, the tool is often a faster, cleaner, and more convenient way of cutting pipe than using a hacksaw, although this depends on the metal of the pipe.
There are two types of pipe cutters. Plastic tubing cutters, which really look much like a pair of pruning shears, may be used for thinner pipes and tubes, such as sprinkler pipe. For use on thicker pipes, there is a pipecutter with a sharp wheel and adjustable jaw grips. These are used by rotating it around the pipe and repeatedly tightening it until it cuts all of the way through.
