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 and a keyed hole in a face of the head;
- and
- a striking insert comprising a second material, a striking surface and a keyed projection coupled to the keyed hole in the face of the head;
- wherein the first material is different than the second material.
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.
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 opposite the striking portion along the transverse axis, 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;
- 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.
