This is done for the players' safety on the pitch. Other methods of bat rolling exist. They do, however, make the bat unlawful to use. Bat shaving is one of these methods that will affect your bat's performance, leading it to be far too hot to play with. Shaving also has the potential to hurt someone if not done correctly. Shaving or trimming the end of your bat removes any protective skin covering which can lead to injuries if a player encounters hard objects while playing. In addition, any unguarded edges on a shaved bat can cause serious injuries if a player is hit in the head by the bat. Protective gear such as helmets are required by law when playing baseball. However, many players choose not to wear them for various reasons. Not only are they expensive, but also distracting when trying to catch balls thrown by pitchers. In conclusion, rolling bats away from players' feet protects them from dangerous objects on the field and ensures they are not used as weapons.
