It's not well said, and it's 100% wrong.
First of all, it is illegal. The links to the prior lawsuit are above.
Secondly, there is nothing illegal about a person doing anything they want to their bat. Taking money for it, however, is how the bat doctors were taken out previously. Again, see the above links. The bat has a trademark on it, and an association stamp that is based on meeting guidelines. Neither of those things are any longer accurate, and if the bat doctors don't remove said marks before returning the bat to their customer they are guilty of breaking counterfeit laws.
Thirdly, I blame the doctors and the users. There is no other way to look at it. It also doesn't matter if the other team has one in their dugout.
I know it's 100% debatable but see it this way...
I crack my bat, have a buddy cut the end, fill it with whatever, pay him for it and use it for BP...you really think my buddy is getting sued for that???
Tell me what's different??? And you can't say he didn't do it for profit because I paid him for it...the bat is ILLEGAL and he altered a bat I paid for with my money...once I buy a bat, IT'S MINE, end of story...if I want to paint it friggin rainbow colors and hit BP with it or hit HR Derby's with it, I can, I bought it, I do whatever I want with it...once it's in my possesion it's mine, END OF STORY...
The bat painters, to hell and back with them, the bat shavers, what can you really do...they are not doing anything illegal to a bat that was purchased by someone...if they are trying to sell it as a LEGAL bat, yes, that's a whole different game...
You can quote laws, court cases whatever you want...the bottom line is once they have a disclaimer that the bat is no longer legal for play, THEY ARE 100% LEGIT in their sales of shaving bats...the disclaimer is there because of lawsuits...without it they are going to get in trouble, with it the bat companies can't do a damn thing...and that's been proven in those cases against previous bat cutters...
Like it or not it won't stop...remember, the shaving guys are NOT passing the bat off as a legal bat, they are dissolved of any litigation by using the correct language in their disclaimers...
IT IS THE END USER, NOT THE SHAVER!!!
