As an aircraft mechanic, and having used speed handles for years to remove panels attached with countersunk machine screws, this would be ideal. Typically use an apex-type holder on the speed handle with the correct size and style tip for the screws to be removed. Nothing works better than a speed handle for providing the necessary torque to remove them, but a large handle on end is often necessary as you place it against your shoulder or chest to hold it tight, and apply torque to the throw. This is especially applicable when removing screws which have been painted since their last installation. The large end of this would be perfect for this application, and the ratcheting ability is a definte plus too. My bet is some intended use like I describe. Never seen one, but would love it in my box!
