It is my understanding that to shave a bat, it requires removing and replacing the end cap. With all the technology and rocket scientists out there: There has to be a way to round off the top of the bat to make it a solid part of the final product. No end cap. The first bat company to develop this construction will probably dominate the market and eliminate the shavers.

I was recently told that rolling a bat leaves marks that can't be removed. If this is true, a rolled bat should be easy to identify.

Except you're missing the big picture. The bat manufacturers don't care about associations rules. They are in this to make money and shaved bats break faster leading to more bat sales.

Kind of like big pharm makes way more money treating illnesses than curing them.

the average person who buy a roller will leave marks on it. The companies that do it for a living don't leave any discernable marks. They know how to do it right so it won't show.

John you are wrong on this assumption. Bat mfg's can tell if a bat has been rolled no matter how it was done or who did it. The inside composite material gets broken down way more than just normal swings on the bat. And yes than can tell.

LB16,

I'm not wrong, your assuming I meant the manufacturers couldn't tell. I was referring to visually inspecting it in person
