Abstract: A chainsaw cutting link (21) comprises: a base portion (29) provided with two rivets holes (20a, 20b) for pivotal inter-connection with adjacent links (13), and a cutting tooth (35) extending away from the base portion (29), wherein the cutting tooth (35) comprises a top plate (41) and a side plate (43) defining an angle to form an L-shaped cutting edge (45, 47, 49) facing in a cutting direction (B). The top plate (41) comprises a top plate cutting edge (45) which is sharper than at least a portion (53) of the side plate cutting edge (47).

Abstract: A cutting chain (300) for a chainsaw (100) may include a plurality of drive links (310) and a plurality of side links (320). The drive links (310) are arranged to lie in a plane parallel to a plane in which a guide bar (120) about which the chain (300) is rotatable lies. The side links (320) are operably coupled to respective ones of the drive links (310) and are oriented to lie in respective planes substantially parallel to the plane. At least some of the side links (320) include cutting portions. The drive links (310) and side links (320) are attached to each other by rivets (360), and the rivets (360) have a longitudinal length that is less than or equal to a width of the side links (320) in a transverse direction.
