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, the head comprising a first material, a striking portion, and a dovetail projection opposite the striking portion along a transverse axis perpendicular to the longitudinal axis;
- and
- a claw comprising a second material and a dovetail connection engaged with the dovetail projection of the head;
- wherein the dovetail projection defines a first width at a first end of the dovetail projection extending towards the striking portion, and a second width at a second end of the dovetail projection extending towards the claw, wherein the first width is less than the second width.
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 along a transverse axis perpendicular to the longitudinal axis, the head comprising a striking portion and a dovetail projection opposite the striking portion along a transverse axis, the dovetail projection having a height extending along the head in a direction parallel to the longitudinal axis of the handle;
- and
- a claw slidably coupled to the head via a dovetail connection, the dovetail connection having a height extending along the claw in a direction parallel to the longitudinal axis of the handle;
- wherein the dovetail projection defines a width that decreases along a length of the dovetail projection as the dovetail projection extends from the claw 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;
- a head coupled to the mounting portion of the handle and extending along a transverse axis perpendicular to the longitudinal axis, the head comprising a second material, a keyed hole in a face of the head, and a dovetail projection opposite the keyed hole, the dovetail projection having a first end extending towards the keyed hole along the transverse axis and a second end opposite the first end and extending away from the keyed hole;
- a striking insert comprising a third material, a striking surface, and a keyed projection opposite the striking surface extending away from the striking surface;
- and
- wherein the dovetail projection defines a width that tapers from the second end to the first end;
- wherein the first material, the second material, and the third material are each a different material.
