Abstract
A hammer is provided that includes a handle, a head, a striking insert, and a claw. The hammer provides for a head with a keyed hole to couple to a keyed projection on a striking insert. The head also includes a dovetail projection that couples to the dovetail connection of the claw. Each component may comprise a different material. For example, the striking insert and the claw comprise one material, and the handle and the head comprise another material. In some embodiments, a slotted punch with a magnetic retainer creates a bore through the face of the head and the striking insert to support a fastener (e.g., a nail) within the head.
Claims22
A hammer comprising:
- a handle defining a longitudinal axis extending lengthwise through the handle, the handle comprising a mounting portion on a first end and a grip portion on a side surface of the handle;
- a head coupled to the mounting portion of the handle and extending in a direction transverse to the longitudinal axis, the head comprising a first material and a keyed hole in a face of the head, and a dovetail projection opposite the keyed hole;
- a striking insert comprising a second material, a striking surface, an inner surface opposite the striking surface, and a keyed projection extending from the inner surface toward the striking surface, wherein the keyed projection is coupled to the keyed hole in the face of the head, an end of the keyed projection—wherein the striking insert further comprises a recess formed in the keyed projection and extending from the inner surface towards the striking surface;
- and
- a claw slidably engaged with the dovetail projection of the head via a dovetail connection, the dovetail projection extending along the head in a direction parallel to the longitudinal axis of the handle;
- wherein the first material is different than the second material;
- and
- wherein the dovetail projection defines a width that varies as the dovetail projection extends from the claw towards the striking insert, and wherein the width of the dovetail projection gradually tapers as the dovetail projection extends towards the striking insert.

A hammer comprising:
- a handle defining a longitudinal axis extending lengthwise through the handle, the handle comprising a mounting portion on a first end and a grip portion on a side surface of the handle;
- a head comprising a first material, a striking portion, and a dovetail projection opposite the striking portion along a transverse axis and extending along the head in a direction parallel to the longitudinal axis of the handle, the head coupled to the mounting portion of the handle and extending along the transverse axis perpendicular to the longitudinal axis;
- and
- a claw comprising a second material and slidably coupled to the head via a dovetail connection, the dovetail connection extending along the head in a direction parallel to the longitudinal axis of the handle;
- wherein the first material and the second material are different materials;
- wherein the dovetail projection defines a width that varies as the dovetail projection extends from the claw towards the striking portion, and wherein the width of the dovetail projection gradually tapers as the dovetail projection extends towards the striking portion.

A hammer comprising:
- a handle comprising a first material and defining a longitudinal axis extending lengthwise through the handle, the handle comprising a mounting portion on a first end and a grip portion on a side surface of the handle adjacent to a second end opposite the first end;
- a head coupled to the mounting portion of the handle and extending along a transverse axis orthogonal to the longitudinal axis, the head comprising a second material, the head further comprising:
- a keyed hole in a face of the head;
- and
- a dovetail projection, wherein the dovetail projection extends along the head in a direction parallel to the longitudinal axis of the handle;
- a striking insert comprising a third material, the striking insert further comprising a keyed projection coupled to the keyed hole in the face of the head, the striking insert opposite the dovetail projection along the longitudinal axis;
- a slotted punch extending partially through the head, comprising:
- a bore extending through the face and the striking insert and extending partially through the head in the direction transverse to the longitudinal axis;
- a punch surface in the head where the bore terminates;
- and
- a magnetic retainer;
- and
- a claw comprising a fourth material and slidably engaged with the head via a dovetail connection, the dovetail connection extending along the head in a direction parallel to the longitudinal axis of the handle;
- wherein the first material, the second material, the third material, and the fourth material are each different materials;
- and
- wherein the dovetail projection defines a width that varies as the dovetail projection extends from the claw towards the striking insert, and wherein the width of the dovetail projection gradually tapers as the dovetail projection extends towards the striking insert.
