Top of the line! All the unfinished wood bats are cut from A-Grade billets and come sanded, boned, and have full barrels with the option to upgrade to prime grade maple with an ink dot. According to the studies, the most fragile point of a bat is located 12 inches from the end of the handle. By placing an ink dot on the fibers, it is this fiber angle which must be measured, and must not exceed three degrees (plus or minus). The ink dot test is actually a safety measure above all. . The measurement of three degrees is very important, especially in the case of maple, because beyond this limit, the fragility of the bat increases exponentially. These tests are carried out at a higher level of play (Big Leagues and affiliated baseball), where the fastballs are predominantly between 90 to 95 MPH and the bat speed also varies between 90 and 95 MPH. The bat then undergoes an impact between 180 and 190 MPH.
