The history of baseball bats dates back to 1800s. During this period, baseball was in its infancy, and players made their own bats from wood, without any specific shape or size; players experimented with long, short, flat, and heavy bats, and they eventually built a bat with a round barrel youth softball bats.
In 1859, the first rule was made regarding the size of the baseball bat. The rule prescribed the allowable width of the bat, 2.5 inches in diameter, but no length was prescribed. In 1869, another rule was made to restrict the length of the bat to 42 inches (the same maximum length allowed today). Even though there was no rule regarding the shape of the bats, most of the players used bats with flat surfaces. Baseball underwent several developments during the succeeding years. In 1890, a committee made a rule concerning the shape of the bat; the rule suggested the round shape of the bat and fixed the diameter to 2.75 inches at the end
Baseball came to a new phase with the introduction of metal belts in 1970. Bats made of aluminum became an instant success, as they are lightweight, durable, and much faster than wooden bats. Although titanium bats were introduced in 1993, they were banned from professional games because of other dangers. Various types of aluminum baseball bats were introduced during the 1990s. Bats made of scandium aluminum are the most popular today.
