The embodiments pictured and described herein are primarily for use with a rotatable hammermill assembly. The hammer includes a connector end having a rod hole therein, a contact end for delivery of energy to the material to be comminuted, and a neck affixing the connector end to the contact end. The neck is formed with at least one neck recess therein. In other embodiments, one or more shoulders are positioned around the periphery of the rod hole for added strength. In still other embodiments, the contact end is configured with more than one contact surface. ## Claims ### Claim 1 A hammer for use in a rotatable hammermill assembly, said hammer comprising: a. a connector end; b. a first shoulder positioned on said connector end; c. a second shoulder surrounding a portion of said first shoulder, wherein said first shoulder and said second shoulder are configured such that a rod hole may be positioned in said connector end within the periphery of said first shoulder and said second shoulder at various positions along the length of said hammer; d. a neck having a first and second end, said neck first end connected to said connector end; and e. a contact end connected to said neck second end. ### Claim 2 (depends on 1) The hammer according to claim 1 wherein said first shoulder is further defined as being generally triangular in shape, and wherein the vertex of said first shoulder generally points toward said contact end. ### Claim 3 (depends on 2) The hammer according to claim 2 wherein said contact end is further defined as comprising: a. a first contact surface; b. an interstitial area adjacent said first contact surface; and c. a second contact surface adjacent said interstitial area. ### Claim 4 (depends on 3) The hammer according to claim 3 wherein the peripheries of said first and second shoulders allow for two inches of adjustment for the placement of the center of a rod hole. ### Claim 5 (depends on 4) The hammer according to claim 4 wherein said hammer further comprises a rod hole positioned in said connector end. ### Claim 6 (depends on 5) The hammer according to claim 5 wherein each side of said hammer comprises a neck recess. ### Claim 7 (depends on 6) The hammer according to claim 6 wherein said hammer further comprises a notch, and wherein said notch is positioned in said first shoulder. ### Claim 8 A hammer for use in a rotatable hammermill assembly, said hammer comprising: a. a connector end; b. a first shoulder positioned on said connector end; c. a second shoulder surrounding a portion of said first shoulder, wherein said first shoulder and said second shoulder are configured such that a rod hole may be positioned in said connector end within the periphery of said first shoulder and said second shoulder at various positions along the length of said hammer; d. a neck having a first and second end, said neck first end connected to said connector end; and e. a contact end connected to said neck second end. ### Claim 9 A method of reducing the weight of a forged, metallic-based hammer while maintaining the strength of said hammer, said method comprising the steps of: a. selecting a width of a neck portion of said hammer to be less than a width of a first end of said hammer and less than a width of a second end of said hammer, wherein said neck portion connects said first end with said second end; b. positioning a rod hole in said first end of said hammer to allow said hammer to pivotally engage a rod; c. configuring said second end of said hammer with a hardened edge; and d. selecting a thickness of said first end of said hammer to be greater than a thickness of said neck portion and greater than a thickness of said second end. ### Claim 10 (depends on 9) The method according to claim 9 wherein said first end is further defined as including a first shoulder formed on a first side of said first end and a second should formed second side of said first end, wherein said first and second shoulders are mirror images of one another. ### Claim 11 (depends on 9) The method according to claim 9 wherein said rod hole further comprises a notch formed therein.
