The term 'Arrows' Partners' is referring to the weapons used in conjunction with arrows, which are SLINGS. SLINGS are a type of projectile weapon typically used in warfare during ancient times. They consist of a Y-shaped frame with a pouch in the middle that holds a projectile, such as a stone or lead ball. The user would swing the sling around their head and release it at the target. SLINGS were used by many cultures throughout history, including the Greeks, Romans, and Native Americans.
