    Abstract: The present invention provides an improved power driven chain saw that includes a device for controlling and eliminating kickback reactive forces. The anti-kickback control device includes a free swinging pivotable attachment that has a distal end portion which is shaped-like a spike or a hook and a proximal end portion which extends longitudinally. The distal end portion is positioned at an angle to the proximal end portion and the spike or hook is used to hold an object to be cut. The proximal end portion is mounted on a pivot member and this assembly is then mounted on the chain saw. The gaff member attachment is designed such that it can engage an object to be cut at an angle and remain therein while an operator pivots the chain saw during a cutting operation.
