Abstract: A flexible interface (130) may operably couple a head portion (110, 210) and a shaft (120, 220) of a hand tool (100, 200). The flexible interface may include a retention assembly (160) and a locking assembly (150) including an actuator (152, 250, 250?) defining a locked state and an unlocked state for the hand tool.
