Abstract
An improved power bark hack including a motor of any suitable type which drives one end of an elongated connecting rod mounted in a co-extensive housing which also serves as the tool handle. The cutter is mounted at the free end of the connecting rod which extends out from the handle or housing. Bearing means, such as buttons made of Teflon which are easily replaced in use, are mounted in the end of the housing closely adjacent the end of the connecting rod carrying the cutting tool, whereby the rotary motion imparted by the motor to the drive end of the connecting rod is changed to substantially pure reciprocatory motion at the cutter blade end.
