The shears further includes a first handle operable to pivot the first cutting blade about the pivot joint and a second handle operable to pivot the second cutting blade about the pivot joint. The pivot joint includes a bolt that extends through the first aperture and the second aperture. The bolt includes a head, a shank that extends from the head, and a longitudinal axis that extends centrally through the head and the shank along a length of the shank. The head includes a concave outer surface that extends around the longitudinal axis of the bolt. ## Claims ### Claim 1 A shears comprising: a first cutting blade including a first aperture; a second cutting blade including a second aperture, the second cutting blade pivotally coupled to the first cutting blade at a pivot joint; a first handle operable to pivot the first cutting blade about the pivot joint; and a second handle operable to pivot the second cutting blade about the pivot joint, wherein the pivot joint includes a bolt that extends through the first aperture and the second aperture, the bolt including a head, a shank that extends from the head, and a longitudinal axis that extends centrally through the head and the shank along a length of the shank, and wherein the head includes a concave outer surface that extends around the longitudinal axis of the bolt. ### Claim 2 (depends on 1) The shears of claim 1, wherein the concave outer surface is located at least partially outside the first and second apertures. ### Claim 3 (depends on 2) The shears of claim 2, wherein the first aperture includes a countersunk portion, and wherein the head is at least partially located within the countersunk portion. ### Claim 4 (depends on 3) The shears of claim 3, wherein the concave outer surface is located at least partially outside the countersunk portion. ### Claim 5 (depends on 1) The shears of claim 1, wherein the pivot joint further includes a nut, and wherein the shank includes a threaded portion engaged with the nut. ### Claim 6 (depends on 5) The shears of claim 5, wherein the head is at least partially located in the first aperture and the nut is at least partially located in the second aperture. ### Claim 7 (depends on 6) The shears of claim 6, wherein the first aperture includes a countersunk portion, wherein the second aperture includes a countersunk portion, and wherein the head is at least partially located in the countersunk portion of the first aperture and the nut is at least partially located in the countersunk portion of the second aperture. ### Claim 8 (depends on 5) The shears of claim 5, further comprising a first washer located in the first aperture between the head and the first blade. ### Claim 9 (depends on 8) The shears of claim 8, further comprising a second washer located in the second aperture between the second blade and the nut. ### Claim 10 (depends on 1) The shears of claim 1, wherein the head includes a recess configured to receive a driver, wherein the concave outer surfaces extends around the recess. ### Claim 11 (depends on 1) The shears of claim 1, wherein the head includes a flat portion perpendicular to the longitudinal axis, and wherein the concave outer surface extends around a periphery of the flat portion. ### Claim 12 (depends on 1) The shears of claim 1, wherein the head includes an outermost periphery located at a furthest distance from the longitudinal axis and surrounding the longitudinal axis, and wherein the concave outer surface extends from the outermost periphery toward the longitudinal axis. ### Claim 13 (depends on 12) The shears of claim 12, wherein the head includes a flat portion perpendicular to the longitudinal axis, wherein the concave outer surface extends from the outermost periphery of the head to the flat portion. ### Claim 14 (depends on 13) The shears of claim 13, wherein the flat portion includes a recess configured to receive a driver. ### Claim 15 (depends on 1) The shears of claim 1, wherein no portion of the head of the bolt extends beyond the first cutting blade measured along the longitudinal axis of the bolt going in a direction from the second blade to the first blade. ### Claim 16 (depends on 15) The shears of claim 15, wherein the pivot joint further includes a nut, wherein the shank includes a threaded portion engaged with the nut, wherein no portion of the nut extends beyond the second cutting blade measured along the longitudinal axis of the bolt going in a direction from the first blade to the second blade. ### Claim 17 (depends on 1) The shears of claim 1, wherein the pivot joint is a first pivot joint, wherein the first handle is pivotally coupled to the first cutting blade at a second pivot joint, wherein the second handle is pivotally coupled to the second cutting blade at a third pivot joint, and wherein the first handle is coupled to the second handle at a fourth pivot joint. ### Claim 18 (depends on 17) The shears of claim 17, wherein the second and third pivot joints include a rivet.
