A method for manufacturing a toothed rotary component (10) having a thickened tooth flank, comprising the steps of: a) manufacturing teeth (3) extending along a plane and uniformly distributed around a blank (1) made of sheet metal material, wherein each tooth (3) has lateral tooth flanks (6) spaced apart from one another by notches (4) distributed around the blank (1); b) deforming at least one tooth flank (6) to manufacture at least one lobe (5), wherein at least one lobe protrudes from the plane of the blank (1), is made of the same material, and protrudes diagonally or vertically upward from the plane of the blank (1); and c) deforming the lobe (5) protruding in the direction of the plane of the blank (1) into a thickened portion (9) of the tooth (3) in the area of ​​the original tooth flank (6).

A forged hammer head (14) formed in a forging process comprises a forged hammer face (20) at one end (22) of the head; a forged hammer claw (36) at an end (23) of the head opposite the face; and a forged side nail puller (45) disposed between the face and the claw. A method for forming a hammer head (14) comprises sequentially placing a blank in a series of cooperating forging dies, and sequentially shaping the blank in the forging dies into a hammer head (14) with a hammer claw (36), a hammer face (20) and a side nail puller (45) disposed between the face and the claw. The side nail puller is configured to engage and pull a nail from a workpiece. The side nail puller comprises a side wall (47) and a notch (49) formed in the side wall. A tool parting line (TPL) of the forging process does not intersect the notch.
