Abstract: A chain saw stabilizing bench is disclosed which permits the sharpening of chain saw cutting teeth under field conditions. The bench consists of an extended planar platform for holding the weight of the saw and an upright holder for securing the saw bar against movement. The bench platform may be supported between upright supports or on any relatively flat surface such as the ground. A fastening means holds the chain saw securely to the bench. A seat at the end of the bench opposite the upright bar holder is provided for the person using the bench and positions the person so that both hands may work the sharpening file while easily and comfortably applying downward force on the file. The weight of the person using the bench keeps the bench from moving.
