Patent ID: 7942428

Claim:
A spark emitting device, the spark emitting device comprising: a housing having an upper surface, a lower surface and a plurality of openings which extend from the upper surface proximate to the lower surface; a respective metal component comprising misch metal inserted in each of the openings in the housing, the respective metal components creating a sparking effect when contacting an abrasive surface; and a double-sided adhesive layer coupled to the lower surface of the housing, wherein a width of the housing surrounding each of the metal components is a maximum of approximately ⅓ of a diameter of the metal component and wherein the housing is composed of a plastic material chosen to wear at substantially the same rate as the metal components, and wherein the housing comprises a multiple platform profile including an upper platform and a lower platform each having a flat top side and a flat bottom side, the bottom side of the upper platform and the bottom side of the lower platform defining the lower surface of the housing and being parallel to one another, and the top side of the upper platform and the top side of the lower platform defining the upper surface of the housing and being parallel to one another on separate planes, the upper platform being positioned on one side of the housing and the lower platform being positioned on an opposing side of the housing, the respective metal components being positioned in the upper platform, and the lower platform being structured thinner than the upper platform and able to flex in response to the housing contacting the abrasive surface.
