Another unusual attachment, called the Handi-Butler introduced with the 1950 Model 510, used the turbine shaft at the front to power several devices, offered as convenience features that could sharpen knives, a cable could also be attached to a wire brush to remove rust from various surfaces, along with a lambs wool polishing disk, and a flannel buffing pad for more delicate tasks. The Handi-Butler was last offered with the Tradition model, and was replaced by the Turbo Sander with the Heritage model. The Turbo Sander was equipped with a small turbine inside the device, powered by the suction through the attachment hose, which can accommodate various grades of sand paper, scrubbing pads, and a soft, vinyl pad to be used as a massage unit that is still currently available.
