64	Chemically machined sheet metal cutting tools and method	US621602	1990-12-04	US5100506A	1992-03-31	James Sturtevant; Jeff Grace; Richard L. Grace
A method is shown for manufacturing a sheet metal tool from a metal blank in which a predetermined pattern of etching resistant material is applied to the back surface of the metal blank to define exposed areas separated by resist areas. A layer of etching resistant material is also applied to the front surface of the metal blank which overlies at least the exposed areas on the back surface of the metal blank. The exposed areas on the back surface are then subjected to etching treatment through the exposed areas to form a tooth shape with a cutting edge. The etching treatment is applied solely from the back surface of the metal blank, whereby the cutting edge is so formed terminate in sharpened surfaces in the plane of the front surface, protected by the layer of the etching resistant material on the front surface of the metal blank.
65	Method and means for making file teeth	US47876674	1974-06-12	US3913420A	1975-10-21	COON JAMES A
A method and apparatus for making file teeth including a punch and anvil that forms part of a die set. A strip of metal is positioned on the die set so that by moving the punch into engagement with the strip of metal, a plurality of file teeth will be formed from the strip of metal.
66	Cutting or abrading elements	US27466572	1972-07-24	US3815189A	1974-06-11	RUSSELL E
A cutting and abrading element of sheet metal has a multiplicity of apertures in arcuate rows with several spaced-apart apertures in each row, the concave side of each row facing the direction of cut, trailing edges of the apertures protruding to form cutting edges. In one embodiment, the circle centres of the arcuate rows are on the longitudinal axis of the element and the space between each pair of apertures in each row is directly behind an aperture in an immediately preceding row and/or directly in front of an aperture in an immediately following row.
