Review on Ultimate Precision: Chef’sChoice 290 AngleSelect Hybrid Knife Sharpener – 15 & 20-Degree Diamond Hone, 3-Stage, Black by David Jones

This brand sells about 30 different electric knife sharpeners. I spent many hours comparing them before purchasing this one. Most models are either 15 degrees or 20 degrees sharpened, but not both. Old American or European kitchen, pocket or hunting knives have a temperature of 20 degrees. Asian knives 15 degrees. Almost all new kitchen knives have a sharpening angle of 15 degrees. I wanted to be able to sharpen both. This model, the Chef's Choice 290, works at both 15 and 20 degrees and does it very well. I have a set of 8 Victorinox knives. Some of them were used very often and needed to be sharpened while the 10 inch chef's knife and the 6 inch fillet knife were never used. Victorinox is known for the sharpness of its knives. In just a minute or two I could make worn knives as sharp as new ones. You cut a piece of paper like a razor blade. If you purchase this sharpener I am sure you will be more than satisfied.
