New from Chef's Choice, get razor sharp edges with an advanced Hybrid technology that combines both electric and manual sharpening. A two stage sharpener; the electric stage sharpens while the manual stage hones, creating a razor-sharp, arch shaped edge that is strong and extremely durable. 100% diamond abrasive wheels are used in both stages and will hold its shape indefinitely. The new and efficient "Criss Cross" technology creates an extremely sharp edge with lots of bite. The sharpening wheels sharpen simultaneously “into” and “out -of” the edge for a superior burr-free edge quickly and easily-no guesswork. The micron size diamond abrasives in Stage 2 ensure a super-sharp polished edge. The Hybrid sharpens both straight and serrated knives; can be used on kitchen or household knives, sport knives, pocket knives and safe for all quality knives.
