  • ice scrapers are conventional and typically include a handle at one end and a scraper blade at the other.
  • a user holds the handle of the ice scraper and drives the scraper blade across a surface from which the user wants to remove ice, such as from the windshield of a vehicle.
  • Conventional ice scrapers are generally relatively difficult to use due to the fact that their design provides for a lack of leverage as well as an awkward positioning of the user's hand during operation. ⁇ s a result, a user is forced to expend much effort and downward force, and is required to work a long time, in order to scrape ice away. Similar is the action to use b conventional squeegee to remove grime and/or bugs from a windshield, window or the like.
  • ⁇ n object of an embodiment of the present invention is to provide a hand held device which is ergonomic.
  • Another object of an embodiment of the present invention is to provide a hand held device which provides for increased leverage during use.
  • Yet another object of an embodiment of the present invention is to provide a hand held device which is easy to use.
  • a specific embodiment of the present invention provides a hand held device which comprises a blade, a forearm brace, and a handle disposed between the blade and the forearm brace.
  • the hand held device may include additional features such as one or more brushes, or one or more foam or sponge wipers, and may take the form of varying shapes, sizes and constructions depending on the application.
