Abstract: A power tool includes a pipe holder, a knife pivotally coupled to the pipe holder, and a drive mechanism coupled to at least one of the pipe holder and the knife. The knife includes a cutting edge having a first portion, a second portion, and an included angle, such as an obtuse angle, between the first portion and the second portion. The first portion of the cutting edge has a first length, and the second portion of the cutting edge has a second length. The drive mechanism is operable to move the at least one of the pipe holder and the knife relative to the other of the pipe holder and the knife. The power tool also includes a motor coupled to the drive mechanism and a power supply electrically coupled to the motor to selectively power the motor for operating the drive mechanism.
