Abstract: The present invention is directed to a razor blade having a non-linear cutting edge and a method for making the razor blade. The razor blade comprises a substrate and a coating layer applied to at least one surface thereof. The coating layer is etched to define a plurality of substantially co-planar cutting edge patterns collectively forming a non-linear cutting edge on the razor blade. Each cutting edge pattern defines an exterior edge having a sharpness sufficient to cut hair. Preferably, a portion of the substrate is removed so that the exterior edges of the cutting edge patterns are offset from the substrate.

Abstract: A method for manufacturing a razor blade. In the method, a razor blade blank is coined to produce a razor blade with a cutting edge. It is preferred that the razor blade blank be unhardened for coining. Additional manufacturing steps that may be performed are hardening of the razor blade at least in the vicinity of the cutting edge, and finishing the cutting edge. The method allows for the cost-effective manufacture of razor blades having both linear and non-linear cutting edges.

Abstract: An apparatus and method for mapping surfaces of an object, such as a structure or vehicle, that utilizes transceivers mounted on portable support structures to orient a probe to form a local global positioning satellite (GPS) system. The probe is placed on reference points of the object and information related to the reference point is input into a data processor. The processor uses the reference points are used to identify and orient the object, and a model of the object is retrieved from memory. Additional position data of the object is gathered and processed to generate a graphical image of the object being mapped. The model is compared to the mapped image of the object and structural damage is assessed. Information relating to repair procedures is output to a workstation and the area under repair can be mapped to evaluate the success of the repair procedure.
