摘要： The technology provides a method of reducing injury to a hamate bone for the lower hand while swinging a bat. The method includes determining a relief location for a knob of a wood baseball bat gripped with two hands, one above the other, with a lower hand being proximate to or contacting the knob. The process includes determining a location of a hamate hook on the lower hand, based on an intersection of a Kaplan's cardinal line and an ulnar border of ring line and placing a transferable substance over the hamate hook of the lower hand. A wooden baseball bat is selected and gripped with the grain positioned for a baseball to contact a hard side of a barrel during a swing. A location is identified to create a relief in the knob based on a transfer of the substance corresponding to a location of the hamate hook.

摘要： The technology provides a device that modifies features of a baseball bat, including a compressing tool that compresses a surface of the baseball bat in a latitudinal direction. The compressing tool includes an implement that pivots along a lengthwise dimension to allow the implement to substantially match a surface angle of an underlying bat barrel. The implement includes a roller that contacts selected portions the baseball bat during a compressing operation. The roller may be sized in a lengthwise dimension to correspond to a surface shape of the underlying bat barrel. The roller may include a surface having any desired surface contour such a convex surface contour, a concave surface contour, or the like. The compressed surface of the baseball bat may substantially assume the shape of the roller surface contour. The barrel may assume a substantially round cross-sectional shape when compressed in the latitudinal direction.
