A hammer comprising:
- a handle, the handle having a bottom end and an upper portion;
- and
- a head disposed on the upper end of the handle, the head having a bell portion and a claw portion;
- the hammer having an overall length dimension and the head of the hammer having a weight measurement;
- wherein a ratio of the weight measurement of the head of the hammer measured in ounces to the overall length dimension of the hammer measured in inches is less than 1.10,
- wherein a bell portion axis extends centrally through the bell portion,
- wherein a longitudinal axis of the hammer extends longitudinally through the handle,
- wherein, in a cross-section that is perpendicular to the bell portion axis and includes an intersection between the longitudinal axis and the bell portion axis, a ratio of (1) a width of the head to (2) a thickness of the hammer is at least 2.6,
- wherein the thickness of the hammer is measured at the intersection between the longitudinal axis and the bell portion axis,
- wherein the bell portion has a maximum bell portion width that is measured perpendicular to the bell portion axis, and
- wherein a ratio of the maximum bell portion width to the thickness of the hammer is larger than 4.6.
