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.
Claims20
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, a dovetail projection, and a keyed hole in a face of the head;
- 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 via a press-fit connection, 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 comprising a third material and slidably engaged with the head via a dovetail connection extending along the head in a direction parallel to the longitudinal axis of the handle;
- wherein the dovetail projection defines a width that varies as the dovetail projection extends from the claw towards the striking surface, and wherein the width of the dovetail projection linearly decreases as the dovetail projection extends towards the striking portion.
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 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 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 linearly decreases 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;
- a striking insert comprising a third material, a striking surface, an inner surface opposite the striking surface, and a keyed projection extending from the inner surface toward the striking surface;
- and
- a claw comprising a fourth material and detachably 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 dovetail projection defines a width that varies as the dovetail projection extends from the claw towards the striking surface, and wherein the width of the dovetail projection linearly decreases as the dovetail projection extends toward the striking surface;
- wherein the first material, the second material, the third material, and the fourth material are each different materials.
