Our newest Hybrid®, the Chef'sChoice® Hybrid® AngleSelect® Diamond Hone® Model 290, provides our most advanced Hybrid® technology for the ultimate razor-sharp edges on all your 15 and 20-degree class knives. Combining electric and manual sharpening stages, it is ideal for sharpening traditional European/American 20-degree class household knives and Asian style and other 15-degree class knives. This affordable sharpener uses angle guides and 100% diamond abrasives in all three stages to apply an extremely sharp, arch-shaped edge that is strong and durable. Using the advanced, efficient Criss-Cross® sharpening technology, the Hybrid® 290 provides a superbly sharp edge with lots of "bite." Its 100% diamond abrasive wheels sharpen simultaneously into and out of the edge for a superior burr-free edge. Stages 1 and 2 are for 20-degree knives. Stage 3 is used for polishing both types of knives as well as for sharpening serrated knives. Safe for all quality knives, the Hybrid® 290 is easy to use, requires no guesswork, and will quickly sharpen even the dullest of knives. It's a stylish addition to any household with its elegant, durable brushed stainless steel cover and sleek design. Engineered and manufactured in the USA.
