Multilayered Ball Bats

A multilayered ball bat comprising:

• an elongated body having a handle portion and a barrel portion and comprising a plurality of substantially planar sheets of substantially uniform thickness, said elongated body comprising:
• a bottom layer comprising a first set of sheets from the plurality of substantially planar sheets, the first set of sheets having a first hardness;
• a top layer comprising a second set of sheets from the plurality of substantially planar sheets, the second set of sheets having a second hardness;
• and
• a middle layer positioned between the bottom and top layers, the middle layer comprising a third set of sheets from the plurality of substantially planar sheets, the third set of sheets having a third hardness;
• wherein the third hardness is greater than the first hardness and second hardness.

A method of forming a ball bat having a bat length and a maximum bat diameter, comprising:

• bonding a plurality of sheets to form a stack having a stack thickness, wherein a sheet thickness of each sheet in the plurality of sheets is substantially similar to the other sheets in the plurality of sheets;
• cutting the stack into a plurality of billets, each of said billets having a thickness of at least the maximum bat diameter, a width of at least the maximum bat diameter, and a length of at least the bat length;
• and
• lathing one of the plurality of billets to form a ball bat having a handle portion and a barrel portion.
