Since 1922, improving shooter accuracy has been a main driver behind Easton archery engineering. To meet that goal, Easton has developed a proprietary process called Acu-carbon™. The Acu-Carbon process is a continuous-fed, single-die manufacturing method that produces uniform shafts and eliminates the need for spine and weight sorting that can plague accuracy-seeking archers and bowhunters. Carbon shafts made this way are used throughout the Easton line and are found in products such as 6.5, AXIS, and FMJ.
