Embodiments are directed toward a bat, such as a softball or baseball bat, that includes a handle and a barrel. The barrel is preferably coupled to the handle. The barrel preferably defines a longitudinal axis. The barrel preferably has asymmetrical composition or construction about the longitudinal axis of the barrel.

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.

Disclosed herein are various forms of hybrid baseball bats comprising a wood shell having a radial wall and an outer radial surface profile defining a baseball bat. The wood shell having a central core with a central surface thereon extending from a distal end of the bat. The central surface being profiled with a taper that in some embodiments extends entirely through to the proximal end. A fibrous construct is housed in the central core and infiltrated with an epoxy resin. In some forms, the fibrous construct is in the form of a sleeve. Disclosed are various manufacturing techniques for manufacturing hybrid baseball bats including a low pressure bladder method, a high pressure bladder method, and a centrifugal force method.

A strung bat for use in playing cricket includes an elongate handle for a user to hold and a blade elongated in the direction of the handle. The blade includes a perimeter defining an internal space that is strung with an array of strings for hitting a ball. The perimeter frame has a leading edge and an opposing trailing edge, and the array of strings lies in a plane that may be substantially aligned with the leading edge of the frame or is closely adjacent to the leading edge of the frame. An apparatus for playing the game using the strung bat is also disclosed.

A bat, which has a hollow barrel and an internal assembly configured to resist deformation of the hollow barrel, is disclosed. The internal assembly includes multiple rods disposed longitudinally within the hollow barrel. The internal assembly can include a deformable ring having a substantially circular outer wall having a diameter less than an inner diameter of the hollow barrel and multiple holes, with each hole configured to at least partially receive a rod of the multiple rods. The bat can have an end cap including end cap holes extending partially through the end cap, with each end cap hole configured to at least partially receive a rod.

A hollow non-wood baseball or softball bat wherein the impact portion of the bat contains an inner multi-walled barrel that is positioned by means of a (i) foam insert, (ii) tube extending from the bat's knob, or (iii) line attached to the bat's knob and end cap and extending throughout the bat such that the inner barrel does not come into contact with the inside wall of the bat when the bat is at rest yet when swung the inner barrel is allowed to move so as to amplify the rebound effect given to the ball upon impact with the bat.
