Patent number: 3945065Abstract: The present invention provides a strong, but lightweight, multi-function, portable lumbering tool which can be easily carried by an individual lumberjack operating alone in the forest. The tool combines a number of functions which permit an individual lumberjack to fell even large trees in a desired direction including a breaking iron for tipping a tree, a wedge for preventing a saw from binding in a partially cut tree, a hook for dragging and rolling felled logs or for freeing a partially felled tree caught on another tree. The tool may also be used as a spade for clearing around the trunk of a tree or for general purpose digging.Type: GrantFiled: June 30, 1975Date of Patent: March 23, 1976Inventor: Victor A. Dushku
