An attachment for a direct drive gasoline or electric powered chain saw for delimbing, thinning, pruning and brushing. The attachment comprises a rigid bar of round cross-section which is secured to the blade of a chain saw at a point spaced a short distance towards the handle from the tip of the blade. When so secured, the bar has a straight portion traversing the flat of the blade at an angle to the longitudinal axis of the blade, extending forwardly and downwardly with respect thereto and upwardly and rearwardly beyond the upper edge of the blade. The bar lies substantially in a plane parallel to the plane of the blade. A second portion of the bar projects beyond the lower edge of the blade and is bent in a gradual curve through an arc radiaus so that its end is parallel to the longitudinal axis of the blade. The bar is secured to the flat of the blade by an appropriate securing device and is preferably spaced from the surface of the blade. A kickback guard is also secured to the attachment to shield the upper front cutting surface of the chain saw from operative engagement with material to be cut. The attachment provides an effective means for cradling small branches and the like to steady them while being cut while at the same time reducing kickback of the chain saw or damage to adjacent foliage or vegetation.
