ABSTRACT:
A sharpening guide for use with a chain saw comprising a support member adapted to rest upon the teeth of a chain in a straddling relationship thereto and having a dependent portion which will extend downwardly in a side by side relationship with the chain saw bar when the support member is in the straddling relationship. A locking member mounted on the support member for movement along a path inclined to the dependent portion so that it may engage the bar or chain of the saw and clamp it against the dependent portion of the support member in a wedging action. A pair of grooved rollers mounted on the support member so as to lie on opposite sides of the chain and of a diameter and disposition so that a file seated in the grooves thereof will be at the required inclination to sharpen teeth at the correct cutting angle.
