A chainsaw guide bar includes a bar body and a nose member removably attached to the bar body by an elastic snap-in coupling, eliminating the need for separate fastening elements. The snap-in coupling includes dimples formed in tongues of the nose member, the dimples being received in holes formed in a web of the bar body. The dimpled portions of the tongues are elastically flexible in a thickness direction of the guide bar to enable the nose member to be inserted or removed.

A nose sprocket for the saw chain of a chain saw includes radially projecting teeth, each tooth having leading and trailing edges. Each of those edges includes a straight inner portion and an outer portion that deviates from a radius of the sprocket by a greater amount than the inner portion. The teeth are long enough to enter a space formed between side links of the saw chain.

A chain saw guide bar allowing spraying of the cut surface of a stump with liquid, is made from three joined plates with a spraying device comprising one or more supply channels provided as cutouts in the central plate. A plurality of spraying holes are provided in one or both side plates. The spraying holes are offset towards the guide bar edge so far that less than the entire area of spraying hole area overlaps the edge of the supply channel.
