Abstract
A hammer has a head connected to a lightweight handle with a center of gravity that is proximate to the head of the hammer and separated from the base of the handle by 85%-95% of the total hammer length, measured from the base of the handle to the top side of the head. The handle weight is between 10%-20%. Accordingly, the lighter handle allows the center of gravity of the hammer to be within 85%-95% of the total hammer length from the base of the handle while maintaining a comfortable head weight between 14 oz. and 25 oz. The hammer also has inflection point proximate to the base of the handle providing multiple gripping sections to allow a user to grip the handle in different locations and at different gripping angles that move relative to the longitudinal axis of the hammer.
Claims20
A hammer, comprising:
- a head having a first longitudinal axis, a striking face perpendicular to the first longitudinal axis, a head length extending along the longitudinal axis, and a top having an end face;
- and
- a handle connected to the head at a side of the head opposite from the end face, wherein the handle comprises an internal composite layer, an external composite layer, and at least one intermediate composite layer between the internal composite layer and the external composite layer, wherein the internal composite layer is formed around an internal core, wherein the handle has a second longitudinal axis substantially perpendicular to the first longitudinal axis, a maximum lateral dimension less than the head length, and a handle length, wherein the head and the handle comprise a total hammer length extending between a base of the handle and the end face of the head, wherein the hammer has a center of gravity proximate to the end face at a location that is 85%-95% of the total hammer length measured from the base, wherein a diameter of the striking face of the head is less than 1.5 times the maximum lateral dimension of the handle, and wherein the internal composite layer and the external composite layer extend the handle length along the second longitudinal axis, wherein the intermediate layer is proximate to the head and extends a length towards the base, and wherein the length is shorter than the handle length.
A hammer, comprising:
- a head having a first longitudinal axis, a striking face perpendicular to the first longitudinal axis, a head length extending along the longitudinal axis, and a top having an end face;
- and
- a handle connected to the head at a side of the head opposite from the end face, wherein the handle comprises an internal composite layer, an external composite layer, and at least one intermediate composite layer between the internal composite layer and the external composite layer, wherein the handle has a second longitudinal axis substantially perpendicular to the first longitudinal axis, a maximum lateral dimension less than the head length, and a handle length, wherein the head and the handle comprise a total hammer length extending between a base of the handle and the end face of the head and comprise a total hammer weight, wherein a handle weight is between 10%-20% of the total hammer weight, wherein a diameter of the striking face of the head is less than 1.5 times the maximum lateral dimension of the handle, wherein the internal composite layer is formed around an internal core, wherein the internal composite layer and the external composite layer extend the handle length along the second longitudinal axis, wherein the intermediate layer is proximate to the head and extends a length towards the base, and wherein the length is shorter than the handle length.
A hammer, comprising:
- a head having a first longitudinal axis, a striking face perpendicular to the first longitudinal axis, a head length extending along a longitudinal axis, and a top having an end face, wherein the striking face is further comprised of a hard substrate, a malleable striking surface, and an embedded grit within the malleable striking surface, and wherein the malleable striking surface is bonded to and is deformable relative to the hard substrate;
- and
- a handle connected to the head at a side of the head opposite from the end face, wherein the handle has a second longitudinal axis substantially perpendicular to the first longitudinal axis, a maximum lateral dimension less than the head length, and a handle length, wherein the head and the handle comprise a total hammer length extending between a base of the handle and the end face of the head, wherein a diameter of the striking face of the head is less than 1.5 times the maximum lateral dimension of the handle, wherein a front side of the handle is comprised of a concave outer surface proximate to the base of the handle and an inflection point at an end of the concave outer surface, wherein the inflection point is located a distance away from the base of the handle, and wherein the distance is less than 5 times the diameter of the striking face.
