The 15 Trizor XV combines the strength and durability of the Trizor edge with the flawless, ultra-sharp 15-degree XV technology. The 15 Trizor XV is suitable for both straight and serrated (wavy) knives and allows for the creation of the Trizor cutting edge on European, American, and Asian blades. It can also convert conventional, factory-made 20-degree edges of household knives into high-performance Trizor XV 15-degree edges. The Chef’s Choice Trizor three-stage sharpening system gives the blade three facets, making the cutting edge stronger. Thanks to the three different bevels formed on each facet, the knives stay sharper much longer than ordinary sharpened edges. The advanced, patented flexible guide system allows for precise control of the sharpening angle. The 3-stage Edge-Select system provides optimal versatility and offers the perfect edge for every cutting task: 100% diamond-coated grinding wheels in stages 1 and 2 for pre-sharpening and sharpening; flexible honing and polishing wheels in stage 3 for a specially sharp cutting edge. It sharpens all kitchen and household knives with straight and serrated blades, as well as modern Asian knives and traditional, simply beveled Japanese knives.
