The tungsten carbine sharpeners of AccuSharp are of high grade industrial quality and are one of the hardest materials known. Even so, after several years of use, they may become worn. Due to their unique design the sharpeners can be reversed for double life.
To use, place knife on table or counter top with the cutting edge up and with about 1/2" of the blade tip extending past the edge of the table as shown in the illustration. While holding the knife handle with one hand, hold the AccuSharp as shown with your fingers through the opening formed by the hangle and the finger gaurd. REMEMBER: THE SHARPENER MOVES WHILE THE TOOL BEING SHARPENED REMAINS STAIONARY.
Straddle the knife's cutting edge near the handle of the knife with the "V" notch formed in the sharpener. WIth the head of the AccuSharp at about a 90 degree angle to the knife's edge press down LIGHTLY using thumb pressure and draw the AccuSharp past the point of the blade. You will feel the tungsten carbide sharpeners removing metal from the knife. Several passes in this manner may be required before your knife's cutting angle conforms to the proper angle of AccuSharp. Once that angle is achieved then two or three passes should be sufficient to bring your knife back to a sharp edge. REMEMBER: LIGHT PRESSURE IS SUFFICIENT. Heavy pressure may cause you to lose control of the knife and possibly cause injury.
AccuSharp is perfectly safe when used properly. As a precaution, the knife blade should be thoroughly cleaned after sharpening.
