forearm centreline 64 with zero degrees achieved when the palm center 66 is in line with the forearm centreline 64 in addition the rounded downward protrusion portion 58 engages the approximate palm centre 66 when gripped although it is contemplated that the palm centre 66 will remain close to the forearm centreline 64 in one embodiment in another it is contemplated to drop approximately 0 5 inches to accommodate a greater wrist angle another way to describe the same structure is that the lower surface spline 50 in the second handle surface portion 56 is configured to maintain a wrist rotation of less than 20 or 30 degrees while keeping the forearm centreline 64 parallel with the shaft centreline 62 the first handle surface portion 54 is then configured to move upwards from the shaft centreline 62 until the forearm centreline 64 is approximately in line with the shaft centreline in still another method of describing the lower surface spline 50 is that the second handle surface portion 56 is configured for proper ease of grip and then the lower surface spline is raised until the shaft centreline 62 and the forearm centreline 64 are approximately aligned this results in an approximate rise of four degrees of the upper surface spline 68 away from the upper shaft plane 24.
