1. A power tool comprising:
a housing;
a motor disposed within the housing and defining a first axis;
a tool holder driven to oscillate about a second axis by the motor, the second axis being perpendicular to the first axis;
a drive mechanism configured to convert continuous torque from the motor to continuous oscillating movement of a tool accessory received by the tool holder; and
a vibration dampening assembly disposed in an interior of the housing, the vibration dampening assembly including a counterweight configured to reciprocate linearly along a third axis perpendicular to both the first axis and the second axis in response to oscillation of the tool holder about the second axis, the third axis being positioned above the first axis defined by the motor.
