Hands-Bat Discussion AGAIN!

[Dukat]

I got into a discussion with my cousin which Umpires baseball about the ball hitting the hands on a swing and going fair. Since I only do softball and he only does baseball I could not quote him a rule for this. For you guys who have a FED baseball rulebook could you quote the hands not being part of the bat rule for me and give me location in book so I can quote him on his book and not mine.
