Zusammenfassung:	An automatic knife sharpening machine may include a vice to grip a blade of a knife and a pair of grind wheels to grind material from the blade. The machine may include a scanner to determine a profile of an edge of the blade, and a sharpness sensor to determine a sharpness level of the edge. The machine may include a controller. The controller may perform a first sharpening pass on the knife by moving the grind wheels into contact with the blade, and advancing the grind wheels longitudinally along the blade from adjacent the vice towards a tip of the blade with the grind wheels in contact with the blade. The controller may determine, using the sharpness sensor, the sharpness level of the edge after the first sharpening pass and perform at least one second sharpening pass when the determined sharpness level is less than a threshold sharpness level.
