An original technique for design based on the combination of human thought and statistical handling of evaluation is described. The unique evaluation point by which the commercial goods were characterized was analyzed using the knives specially designed from the view point of preciseness. Then the relation between the features of the unique point and common recognition of the impression was discussed. The impression of samples was sensory evaluated using a scale composed of several estimation items. The distribution diagram of data was described and a sample which locates in an unique position in the diagram was selected and called a sample of the singularity. The feature of impression for the singularity sample was analyzed by means of the statistical method. An improved sample emphasized the feature was newly designed, and was sensory evaluated with the same set of evaluation scale. Repetition of this process will make surer in respect of the recognition of the impression for the design
