Abstract
An electric sharpener having two pairs of interlocking abrasives for sharpening the edge of blades to different sharpening angles. An adjustment assembly simultaneously moves the wheels of each pair either toward or away from each other to adjust the sharpening angle produced by pair of abrasive wheels in a sharpening operation. The adjustment assembly is provided with a rotatable shaft having an external handle which engages a lower platen. The lower end of the shaft is threaded to move the platen in vertical direction to move translation bars affixed to the platen. The translation bars extend through elongated slots in respective pairs of adjustment arms coupled to each pair of abrasive wheels to rotate and vary the spacing between the abrasive wheels and adjust sharpening angles.
