Abstract of the Disclosure A guide bar for a chain saw having a main body portion that is symmetrical so as to be invertible, i.e., to reverse the top and bottom edges, and including a nose portion having fixed top and bottom positions that is removably attached to the outer end of the main bar portion. Said nose portion is non-symmetrical with the upper quadrant of the nose sharply curved away from the top edge and the lower quadrant gradually curved back to the bottom edge. Whereas the main body portion can be inverted, the life of that portion of the bar is greatly increased.
