Abstract
The object of the invention is a flat file which is suitable for lifting off films from intermediate layers.
Claims5
A flat file comprising:
- a file handle;
- a file tang;
- a flat file blade extending from a first end to a second end;
- wherein the file tang extends from the first end of the flat file blade;
- wherein the flat file blade comprises an upper surface extending from the first end to the second end, a lower surface extending from the first end to the second end, a first side surface extending from the upper surface to the lower surface, a second side surface extending from the upper surface to the lower surface, and a flat end surface at the second end;
- wherein the flat file blade comprises a cutting bevel having a bevel surface and a ricasso,
- wherein the bevel surface extends from the upper surface toward the lower surface, intersects the first side surface to define an inclined edge and intersects the flat end surface to define an inclined edge;
- and
- wherein the upper surface has a single-cut, cross-cut or a rasp cut.

A process for peeling of films of a shim using a flat file having a flat file blade comprising an upper surface extending from a first end to a second end, a lower surface extending from the first end to the second end, a first side surface extending from the upper surface to the lower surface, a second side surface extending from the upper surface to the lower surface, and a flat end surface at the second end;
- wherein the second side surface and the flat end surface intersect to form a tip, further wherein the flat file blade comprises a cutting bevel having a bevel surface and a ricasso, and wherein the bevel surface extends from the upper surface toward the lower surface, intersects the first side surface to define an inclined edge and intersects the flat end surface to define an inclined edge, the process comprising:
- scratching one or more films, composed of metal or plastic, by the flat file causing the one or more films to be partially lifted off;
- subsequently further lifting the lifted-off film or films with the cutting bevel;
- subsequently breaking the lifted-off film or films with the tip;
- subsequently supporting an end of the broken film or films with the cutting bevel;
- and peeling off the broken film or films.
