Chef's Choice 120 Diamond Hone 3-Stage Professional Knife Sharpener, White

I've owned a couple of Chef's Choice Sharpeners over the years.  I used to schlepp them with me when I taught cooking and knife skills classes (for charity).  And even though I learned to sharpen my knives on bench stones more than forty years ago, and still use them as my primary sharpening system, for more than a year -- when between bench stone kits -- I used a model 110 as my primary sharpener.

Among many self-proclaimed "knife experts," electric knife sharpeners have a very bad reputation.  Many years ago the reputation was deserved.  However, the Chef's Choice was the machine that changed that.  Used properly -- something very eas to learn -- a Chef's Choice will not harm your knives.

This particular class of Chef's Choice creates something the company (Edgecraft) calls a "trizor" edge.  That means a multi-bevel shape which is stays sharp a long time and is very resistant to deformation. 

On the other hand, there are two ways to get a knife sharper -- even much sharper.  But bench stones require surmounting a steep learning curve (bench stones), and is inconvenient; and tool and jigs like an Edge Pro are easier to learn than stones but still more convenient.

Considering the ease of use and convenience, a Chef's Choice has no competition when it comes to sharpness.  And, even the most expensive Chef's Choice machine is less expensive than a good set of stones or an Edge Pro.   

Bottom Line:  The least good of the three good ways.  If you can't use stones, and don't want to put up with setting up and taking down an Edge Pro, not to mention the price; if you want something convenient enough to use whenever you need to use it, something which is absolutely procrastination proof -- this is it.

Although I own a Model 100 (got it just before The Cretaceous Period).  It took a bit of getting used to, but it now provides me with the next best thing to a professionally sharpened knife.  I'd recommend this sharpener to everyone.

I've never been able to master sharpening my knives with a steel. I nearly ruined my Henckel knives trying to sharpen them myself. So for years I took my knives to a professional sharpener whenever they became dull. Finally, I splurged and bought the Chef's Choice 3-stage electric sharpener and never looked back. It was a great investment for me; my knives are always sharp now and ready to take on whatever slicing, dicing or chopping job I need done.
