Abstract
A gulletless saw chain having a cutting link with a cutter portion that is configured to be top sharpenable. A depth gauge portion is positioned in close proximity to the cutting edge corner of the cutter portion. The depth gauge is laterally offset to position the outer most edge of the depth gauge at the corner of the cutting edge to thereby control side penetration as well as depth penetration of the cutting edge. A drive link preceding the cutting link includes a guide portion with an inclined leading edge that corresponds with the leading edge of the depth gauge. A shallow V shaped opening is formed between the depth gauge and drive link guide portion to assist the cutting link in tracking in the kerf.
