Saw chain

A saw chain defining a center plane, the saw chain comprising:

• a plurality of connecting links and a plurality of drive links arranged between mutually adjacent ones of said plurality of connecting links;
• a plurality of rivets defining respective rivet axes;
• said plurality of rivets connecting said plurality of connecting links and said plurality of drive links in an articulated manner about said rivet axes;
• each of said plurality of connecting links and each of said plurality of drive links having rivet openings;
• each of said plurality of rivets projecting through two of said rivet openings of two of said plurality of connecting links and through one of said rivet openings of one of said plurality of drive links, wherein said rivet, at least in a region of said one rivet opening of said drive link, projects between said two connecting links;
• each of said plurality of rivets having a collar arranged in corresponding ones of said rivet openings of corresponding ones of said plurality of drive links without projecting into corresponding two adjacent ones of said rivet openings of corresponding ones of said plurality of connecting links;
• said center plane running perpendicularly to said rivet axes and centrally through said plurality of drive links;
• selected ones of said plurality of connecting links being configured as cutting links with said cutting links having respective cutting sections;
• said plurality of rivets each having first and second end faces and a core diameter (d);
• said first and second end faces being formed on first and second rivet heads having an enlarged outer diameter (b);
• said first and second rivet heads project over an outer surface of corresponding ones of said plurality of connecting links;
• at least one of said plurality of rivets having a depression formed in at least one of the end faces thereof, wherein said depression has a convexly curved base of said depression;
• said at least one of said plurality of rivets being configured as a solid body;
• and,
• said first and second end faces are configured so as to be different from one another, wherein the first end face is convex shape.
