Claims29
A hammer comprising:
- a handle having a bottom end and an upper end, the handle comprising a steel core portion and a manually engageable grip portion surrounding a part of the steel core portion, the grip portion comprising an elastomeric material, a rubber based material, or a plastic based material;
- and
- a steel head disposed on the upper end of the handle, the head having a steel bell portion and a steel claw portion,
- wherein a bell portion axis extends centrally through the bell portion,
- wherein the bell portion has a maximum side-to-side bell portion width that is measured perpendicular to the bell portion axis,
- wherein a longitudinal axis of the hammer extends longitudinally through the handle,
- wherein the hammer has a first thickness defined as a maximum side-to-side thickness measured perpendicular to and through the bell portion axis in an area between a forward boundary disposed 5 mm forward of the longitudinal axis and a rearward boundary disposed 25 mm rearward of the longitudinal axis, and
- wherein a ratio of the maximum bell portion width to the first thickness of the hammer is larger than 4.6.

A hammer comprising:
- a handle having a bottom end and an upper end, the handle comprising a steel core portion and a manually engageable grip portion surrounding a part of the steel core portion, the grip portion comprising an elastomeric material, a rubber based material, or a plastic based material;
- and
- a steel head disposed on the upper end of the handle, the head having a steel bell portion and a steel claw portion, wherein a bell portion axis extends centrally through the bell portion,
- wherein a longitudinal axis of the hammer extends longitudinally through the handle,
- wherein the hammer has a first thickness defined as a maximum side-to-side thickness measured perpendicular to and through the bell portion axis in an area between a forward boundary disposed 5 mm forward of the longitudinal axis and a rearward boundary disposed 25 mm rearward of the longitudinal axis,
- wherein the hammer has a claw thickness defined as a maximum side-to-side thickness of the hammer within a portion of the hammer disposed above the bell portion axis and between the forward boundary and rearward boundary, and
- a ratio of the claw thickness to the first thickness is at least 2.0.

A hammer comprising:
- a handle having a bottom end and an upper end, the handle comprising a steel core portion and a manually engageable grip portion surrounding a part of the steel core portion, the grip portion comprising an elastomeric material, a rubber based material, or a plastic based material;
- and
- a steel head disposed on the upper end of the handle, the head having a steel bell portion and a steel claw portion,
- wherein a bell portion axis extends centrally through the bell portion,
- wherein the bell portion has a maximum side-to-side bell portion width that is measured perpendicular to the bell portion axis,
- wherein a longitudinal axis of the hammer extends longitudinally through the handle,
- wherein, in at least one lateral cross section that is parallel to the longitudinal axis, disposed no more than 5 mm forward of the longitudinal axis, and disposed no more than 15 mm rearward of the longitudinal axis:
- the hammer has a first thickness defined as a maximum side-to-side thickness measured within the at least one cross-section in a region of the cross-section that is disposed between the bell portion axis and a point 60 mm below the bell portion axis, and
- a ratio of the maximum bell portion width to the first thickness of the hammer is larger than 4.6.
