Abstract: A multiple edged blade has at least two blade edges contacting a window surface simultaneously. A washing sponge in between the edges receives liquid from a central conduit. Various smooth and serrated planes adjacent to each edge provide alternative working edges for different conditions of the window. A hard pointed edge cuts through ice. A sharply angled forward edge of the blade scrapes. A centrally positioned sponge washes. A rearwardly pointing rear edge wipes. A rotatable triple edged blade with multiple types of surfaces provides versatility for use in any weather.

Abstract: A filtering/heat-reduction smoking apparatus for various tobacco products. A convoluted passageway in the apparatus removes tar and other harmful chemicals and reduces the heat of the smoke thereby increasing the user's pleasure. Air intake holes also aid in reducing heat. The design requires the smoke to travel through a convoluted passageway many times greater than the length of the apparatus. The apparatus disassembles quickly and easily for cleaning.
