Abstract: A power tool includes a housing assembly, a motor, a pipe holder, and a knife pivotally coupled to the pipe holder at a pivot point for movement relative to the pipe holder. The knife is operable to pivot through an angle toward the pipe holder during a cutting motion and is operable to pivot through the angle away from the pipe holder during a return motion. The power tool also includes a drive mechanism having a first gear coupled to the motor and a second gear coupled to the knife. The power tool further includes a release mechanism coupled to the drive mechanism. The release mechanism is operable to selectively disconnect the second gear from the knife so that movement of the motor is not transmitted to the knife and the knife is movable through the angle away from the pipe holder.

Abstract: A cutting tool includes a housing and a pair of cutting blades at least partially extending from the housing. At least a first of the cutting blades is movable. The cutting tool also includes a drive mechanism including a cam and a ratchet mechanism. At least a portion of the ratchet mechanism is drivably coupled to the first cutting blade. The cutting tool further includes a motor for providing torque to the cam to actuate the ratchet mechanism.
