This study aims to develop hair cutter with zirconia($ZrO_2$) material whose machinability, corrosion resistance, wear resistance and bio-compatibility are excellent by comparing iron hair cutter. Ultra-thin zirconia cutter with the thickness of 0.253mm is manufactured through the optimization of design, molding, sintering, grinding and grinding process. With observation result of cutter specimen by use of scanning electron microscope(SEM), formability and process of cutting face are shown to be good. It is also evaluated with sufficient merchantability by cutting test results. The cutter process technology of thin zirconia can be utilized at the development of high value-added beauty appliances like razor, beauty-razor and eye brows-razor for woman by use of study result.
