The present invention provides an adjustable blade sharpening apparatus for sharpening cutting blades by controlling the positioning of the blade relative to the grinding wheel to produce multiple facets on the cutting blade with a substantially burr-free cutting edge and method of controlling the angle of and position of a blade employing the blade sharpening apparatus. The blade sharpening apparatus comprises a fixed base supporting a table surface including a vertically mounted rotary grinding wheel mounted on an axle and having a circumferential peripheral cutting edge. A blade guide is provided mounted by a pair of arms on the axle for accurate movement between a lower grinding position and an upper grinding position being supported by an adjustable vertical support member for adjustment of the radial positioning of the blade guide, the support member firmly holding the blade guide in a preselected position for positioning a knife blade in angular relationship with the cutting edge of the grinding wheel holding the cutting edge of the blade in spaced relationship with the arms of the blade guide to permit sharpening of the blade without producing a burr on the cutting edge.
