You’ll know you’re reached a stopping point when you can feel the slight catch of the bevel on the edge of the blade, by carefully running your finger in the direction of the blade, or by cutting through a sheet of paper. When the knife cuts cleanly through the paper, it’s time to hone the blade. Read our guide for more information about honing vs sharpening.
By employing separate sharpening slots, the ProntoPro 4643 is capable of sharpening both older European-style knives (such as from Wüsthof and Henckels) and Japanese-style knives (such as from Mac—which makes our favorite chef’s knife—and Shun). The difference is in the angle of the bevel that forms the cutting edge: Traditional European knives have roughly 20-degree bevels, while Japanese knives have roughly 15-degree ones. If you own both types of knife, or if you do a lot of heavy work in the kitchen (like chopping up chicken carcasses), you’ll appreciate this feature, as a 20-degree bevel is best for tough jobs. Note, though, that Wüsthof and Henckels have stopped making 20-degree knives, having switched to 15-degree or 12-degree designs exclusively in 2011; the reason is that for all but the heaviest tasks, these more-acute bevels cut better and, with the ongoing improvements in steel alloys, hold their edges for just as long.
I bought this knife sharpener for my son as a Christmas present years ago and recently (but cautiously) used it on my cutlery (Henkel and Wusthof). Frankly, I had been a little lazy and let my knifes lose a bit of their edge. I did not feel like getting out my stones and oil to do a proper job, so I borrowed my son's sharpener. It really works great, which I hate to admit, as it feels like a cheat and it is a fraction of what I spent on stones. I realize that I need to buy one for myself, so I looked around to see if there is anything better and I could not see anything that looked better. This one is adjustable, which is what I need. I looked at the 1 star ratings and there was a common theme that the knife edge chatters as the blade is pulled across. It can, if you don't use it properly! If your blade is very dull, you will need to pull with a very light, steady, and quick motion. You never need to push down hard as you pull. Even pressure. Don't be a brute! Finesse is what is needed. I am going to buy another one for me.
The Chef’s Choice 120 sharpener features three stages of sharpening. You can easily select between rough grit, fine grit, or honing. Rough grit is best for those extremely dull blades that will not cut through anything whatsoever, or blades which have been damaged and pitted. You can choose to follow that stage with the second and third stages or skip right to the third. Personally, I find it isn’t necessary to use every stage every time – that only chews up your blade faster, causing it to shrink.
Today, however, there is a whole new generation of mechanical sharpeners that are far more forgiving for those who may not use perfect technique. At the same time many more people have become accustomed to sharpening their knives this way and the average novice of 10 years ago is now the seasoned pro. It is still possible to damage knives with an electric sharpener, but you would have to either be trying to damage the knife or have some type of accident in order to do so.
There are many methods to sharpen your knives. For example, you can use a sharppening stone, or a sharpening rod, sharpening system or an electrical sharpening machine. You can also ask someone else to do the job. The best sharpening method for you, depends on the kind of knives you want to sharpen, the type of steel of the blade, your experience with sharpening and your own preferences.
As noted above, both Chef’sChoice and Cook’s Illustrated advocate using the Trizor XV to convert 20-degree knives to the arch-shaped 15-degree edge, so if you have European-style knives, you can still use this machine confidently. You can also use the final honing stage to “strop” serrated knives—helping to keep the teeth polished and aligned—but the Trizor XV cannot resharpen them.
Meanwhile, if you want something that you can use to sharpen a variety of knives and edges, including small and pointed tools, you might want to consider the DMT WM8CX-WB 8-Inch Duo Sharp Plus Bench Stone – Coarse/Extra Coarse with Base. For less than a hundred bucks, you can even use it to repair a damaged edge because of its extra-coarse diamonds.
It takes time to sharpen a knife correctly. I spent about 30 minutes on an already fairly sharp knife. I then spent two more sessions of about 10 to 15 minutes each. I took it a bit further with a 6000 grit stone and this puts a nice polish on it. Instead of cutting through an onion, it glides or slips through it. It was truly shocking to me to use a really sharp knife. It may take a bit of time to get it right the first time, since this was my first time with a water stone, but it was well worth the effort. I have been trying to figure out the best way to get a really sharp knife.

Lubricate the stone. Some stones specifically use oil or water, and if that's the case, ensure you're using the recommended lubricant. Most importantly, whichever lubricant you choose, do not change it after the first use. When using oils, only use those approved for sharpening stones. Food oils such as vegetable and olive oil should never be applied! Some options like diamond stones, and others, don't need any lubricant at all, so be sure to check the stone's instructions.
