ABSTRACT ARM CONTROLLED POWER CUTTER A portable power cutting apparatus has a control unit with a support for mounting the control unit on one arm of the user permitting the control unit and cutting tool to be supported by that arm. The support is pivotal and a flexible cable operatively connects a motor to the cutting tool for driving the tool. This permits the control unit to be pivoted in a lateral direction or twisted to allow the operator to move the cutting head in a variety of positions without loss of power by moving only the supporting arm and hand of the user. A handle is provided on the control unit for gripping by the hand of the user's support arm. A cutting tool suitable for girdling a tree and which can also be used to cut through tree branches and small tree trunks is also disclosed. This cutting tool is frustoconical in shape having a length of chainsaw chain wrapped in a spinal groove around the outside face of this tool body. In another embodiment the cutting tool is a chainsaw which can be operated with the supporting arm of the user.
