Abstract

A knife sharpener comprises: a grinding block (22) mounted on a vertical axle and having a horizontal grinding surface (26); a motor (21) arranged to rotate the grinding block (22); one or more guides (10,11) pivotally mounted on a support and adapted to receive the blade of a knife so that the cutting edge of the blade contacts the grinding surface (26); and an adjustment mechanism arranged to adjust the angle of the guides (10,11) relative to the grinding surface (26).
