Bone Rubbing
"Boning" bats began in the earliest days of baseball. The Hall-of-Famers
spent hours in their dugouts rubbing their bats with old cow femur bones. Bone rubbing
closes the wood's pores, compressing it and making it harder.

Marucci uses the same technique Babe Ruth and Lou Gehrig used on their bats, rubbing
before the finish is applied to seal and harden the wood. Using cow femurs from
Sandy Farms, Iowa, Marucci takes his time on this step, and the same pride in it
his baseball heroes once did.
