Abstract
Striking tools are disclosed that include a handle and a head. Striking surfaces may be securely attached to the head. In this way, lighter weight striking tools may be made with greater durability.
Claims20
A striking tool, comprising:
- a handle with a first end and a second end;
- a head disposed on the second end, the head comprising a receiving surface;
- a cap attached to the head and comprising a mounting surface;
- a length of engagement between the mounting surface and the receiving surface;
- a first perimeter of engagement measured around the receiving surface at a first point along the length of engagement distal from the cap;
- and
- a second perimeter of engagement measured around the receiving surface at a second point along the length of engagement proximal to the cap,
- wherein a ratio of the length of engagement to the difference between the first perimeter of engagement and the second perimeter of engagement is greater than about 0.4.

A striking tool, comprising:
- an aluminum head, the head including an extension, the extension having a receiving surface, the receiving surface tapered at an angle along a side of the receiving surface of about 10 degrees or less;
- and
- a cap including a first side and a second side opposite the first side, the first side comprising a striking surface, the second side including a hollowed portion, wherein the hollowed portion includes a mounting surface,
- wherein the extension is received in the hollowed portion of the cap, the receiving surface in contact with the mounting surface along a length of engagement to permanently affix the cap to the extension via a friction fit,
- wherein a first perimeter of engagement is measured around the receiving surface at a first point along the length of engagement, a second perimeter of engagement is measured around the receiving surface at a second point along the length of engagement, the first point farther from an end face of the extension than the second point, and a ratio of the length of engagement to a difference between the first perimeter of engagement and the second perimeter of engagement is greater than about 0.4.

A hammer, comprising:
- an aluminum head including an extension having a longitudinal axis, the extension including a receiving surface and an end face, the receiving surface tapered at an angle of less than 10 degrees along a side of the receiving surface relative to the longitudinal axis;
- and
- a steel cap including a hollowed portion, the hollowed portion including a mounting surface, wherein the extension is received in the hollowed portion such that the mounting surface is permanently affixed to the receiving surface via a friction fit,
- wherein a length of engagement exists between the mounting surface and the receiving surface, a first perimeter of engagement is measured around the receiving surface at a first point along the length of engagement, a second perimeter of engagement is measured around the receiving surface at a second point along the length of engagement, the first point being farther from the end face of the extension than the second point, and a ratio of the length of engagement to a difference between the first perimeter of engagement and the second perimeter of engagement is greater than about 0.4.
