Sharp edges on biometerials are difficult to produce and maintain. Medthin coatings will enhance the life of a device or instrument by providing a surface that is harder, with a much better edge retention and improved corrosion resistance. In addition to oustanding hardness and superior wear resistance, sharp edges generate less heat during the cutting process and hence reduce the tendancy for cell necrosis. Additionally, providing a clear cut, promotes faster healing. Instrument life increases of as much as 800% have been reported.
