The present invention provides a hand-held striking tool that has a head disposed forward of the centerline of a handle. The hand-held striking tool of the present invention may further include a flange positioned beneath the head of the tool, the flange functioning as a second area of contact so that the effect of overstrike may be controlled. The present invention also provides a hand-held striking tool that isolates the striking head of the tool from the handle such that the effect of vibrations caused by using the tool are reduced.

The striking tool of claim 15, wherein the top of the head is substantially curved over a continuous radius.26. The striking tool of claim 24, wherein the top of the forged head is substantially curved over a continuous radius.27. The striking tool of claim 20, wherein the unitary piece encases a pultrusion.28. The striking tool of claim 27, wherein the pultrusion is a pultruded rod.29. The striking tool of claim 1, wherein the head is cast.30. The striking tool of claim 1, wherein the head is machined.31. The striking tool of claim 15, wherein the head is cast.32. The striking tool of claim 15, wherein the head is machined.33. The striking tool of claim 3, wherein the generally curved handle and the generally curved shank have a common continuous radius.34. The striking tool of claim 17, wherein the generally curved handle and the generally curved shank have a common continuous radius.35. A striking tool comprising:a handle; a head, the head defining a striking surface, the head further defining a weight center; and a generally curved shank connecting the handle to the head, the generally curved shank defining a curved centerline; wherein the weight center is disposed between the curved centerline and the striking surface; wherein a horizontal plane is defined as the plane on which the striking tool rests when laid flat on its side; and wherein a first cutting plane divides the striking tool along the length of the striking tool, wherein the first cutting plane is perpendicular to the horizontal plane; and wherein a line which is intersected by the first cutting plane is defined by a first point positioned along a center line of the handle and a second point positioned along the center line of the handle, wherein the second point is vertically 2 inches up the handle as measured from the first point, and wherein the first point is separated by a vertical distance of 2 inches from a bottommost point, wherein the bottommost point is defined by a bottom edge of the handle, and wherein the bottommost point is intersected by a line that is parallel to the first cutting plane. 36. The striking tool of claim 35, wherein a top edge of the head defines a center point, wherein a second cutting plane which is perpendicular to the first cutting plane is disposed 2 inches down from the second center point.37. The striking tool of claim 36, wherein a head portion is defined by the second cutting plane, and wherein the head portion is further divided by the first cutting plane into a first region and a second region, wherein the first region is proximal to the striking surface, and wherein the second region is distal to the striking surface.38. The striking tool of claim 37, wherein the weight of the first region is between 70 and 90% of the sum of the weights of the first and second regions.
