Abstract:

A method and a gauge for measuring the sharpness of the tip of an object is provided. The method includes receiving the tip of the measured object in the end of a tube. The object deflects a plunger inside the tube a finite distance proportional to the sharpness of the object inserted in the tube. A measurement of sharpness of the tip of the object is derived by measuring the deflection distance of the plunger. The measuring method may be used to measure the sharpness of a number of objects in sequence by displaying the sharpness of the object, such as where the objects being measured are pins arranged in a matrix pattern.
