Abstract
A blade sharpness detection system for determining a sharpness of a blade without mechanical contact with the cutting edge of the blade. An optical inspection unit is operative to inspect blade sharpness optically, and a blade positioning and guidance mechanism is disposed to position and guide the blade in relation to the optical inspection unit. An output display is operative to provide a visual output of the sharpness of the blade. The optical inspection unit, which can be a reflective optical sensor, and the blade positioning and guidance mechanism are retained by a pivotable support structure. The positioning and guidance mechanism can be formed by first and second pairs of rotatable spheres, each pair of rotatable spheres disposed in immediate juxtaposition to act as rolling supports for the blade.
