The Chef'sChoice® Model 1520 will easily sharpen virtually all quality cutlery, including American, European or Asian style household knives; fine edges or serrated blades, Santoku and traditional Japanese style single-bevel edges including the thicker Deba style blades; as well as sport knives and pocket knives. This patented advanced technology electric sharpener can restore and recreate both a 20 degree edge for traditional European knives and a 15 degree edge for Asian style knives and contemporary European/American style knives.
The Model 1520 works by using different combinations of the 3 stages to achieve it's result. To sharpen knives to a 15 degree angle, Stage 1 and Stage 3 are used. To sharpen 20 degree class knives, Stages 2 and 3 are used. The initial stages sharpen and hone the edge using 100% diamond abrasives, while Stage 3, which is similar to a barber's strop, polishes the edge with a flexible disk for a super sharp edge. Stage 3 is also used to sharpen serrated knives.
