I’d like to clarify the difference between the two Wahl clippers: the Wahl Senior and the 5 Star Senior. The main difference lies in the blades. The 5 Star Senior comes with a #2191 Fade blade that cuts closer and handles fading or tapering better than the classic #1005 blade found in the Wahl Senior. They both run on the same powerful V9000 motor, but have slightly different functionalities due to their blades.
