I've been uging it for years and it still works well
5 Stars
I've been uging it for years and it still works well
I like that it is set up for either Asian or Euro/Amer for the coarse sharpen and, being left handed, that it works equally well for lefties and righties.The updated version, now lists 15 degrees and 20 degrees instead of Asian and Euro/Amer. 15 = Asian and 20 degrees = Euro/Amer (See photos). Under the current listing, the first video shows just pulling the knife towards you and the second video shows pushing and pulling. I've always used the push/pull method, but, since the first video is from the manufacturer, I plan on trying the pull method instead.One last piece of information. I still finish off my sharpening process with a diamond carbon steel sharpening rod that is also available on Amazon.

I have some mediocre knives that had gotten dull over the years. This sharpener really worked on them and I think they are sharper than new. Easy and fast to use. There is a slot for 15° and 20° knife edges. I haven't figured out a way to accurately measure the angle so I'm assuming my old US and German knives are 20°. Ocassionally there is an annoying squeaking noise when I use the sharpener but it only takes a few strokes to sharpen a knife so it isn't a big deal.

I've owned a Chef's Choice electric sharpener since the 1980's, but that has only a fixed pitch angle for European-style blades. With a recent purchase of a Japanese-style chef's knife, I needed a new sharpener. This sharpener has served well. It takes some patience, as it may take more pulls than recommended in the manual, but the result is quite sharp. The convenience of a hand-held sharpener that you don't have to plug in has helped me to sharpen more often, too. Works well for both my European-style and Asian-style knives.
Reviewed in the United States on April 20, 2024
This device is great for USER knives that need touch-ups or maintenance sharpening. If you have designer knives or expect your bevel surfaces to be museum pristine condition after use - than this is not the device for you.

Also, don't expect this device to reset your bevels from the factory if you have your knife is extremely obtuse or uneven edges on both sides - you will dull your edge - until you spend the correct amount of time to thin down your bevels so that the edge is finally apexed. This is a touch-up or maintenance sharpening tool, not a re-beveler or reprofiling device. If you have chunks of metal missing on your edge, don't expect this device to smooth out your edge, that is a complete reset of the bevel which this device is not designed to complete. If you are meal prepping for 20 mouths, 24/7, again - this device isn't for you. It may say "professional" but it's for personal home touch-up/maintenance use, not to run a side hu$tle.

I've resharpened over the past 24 months:
*4 different branded folder knives
*1 spyderco z cut
*2 generic sub-$100 santokus

For knives that I have already reset bevels or knives with extremely factory even bevels, this device has replaced my Spyderco Sharpmaker for touch-ups. Even though the Chef'sChoice 4643 takes off a lot more steel than the Sharpmaker, it's at least as fast or faster. Since there is no setup time compared to the Sharpmaker (which only takes about 60 seconds), touch ups are almost instantaneous. This is great for AIRBNB knife rescues when you think it might be safety issue when the edge doesn't bite enough. But again - if you run into a knife that is duller than a spoon, this device isn't for you. And no, this will not sharpen a cleaver (I checked for science).

Cons: It's difficult to keep the wheels clean. The cleaner they are, the less chance of accidental marring on the knife sides and the easier it is for the wheels to touch up the edge.

This brand is regularly awarded top-performer or best-value by America's Test Kitchen.

We were happy with the older diamond draw-through sharpeners for years but its 20-degree edge is not very sharp. We jumped on Chef's Choice electric-powered sharpener because its sharpening disks left cross=wide scratches (a micro-serration) rather than lengthwise. That sharpener took up space and had to be plugged in. I had to hunt for it.

This manual sharpener uses the same diamond disks as the powered version at a much lower price. It also can live on a convenient shelf.

My wife has a professional-grade chef's knife with that Japanese 15-degree edge. While it stays sharp for months, it does eventually require sharpening and this sharpener does restore the edge.

I have premium name-brand knives that appear narrow and sharp initially but have a much less acute edge than the advertised 20-degree. This sharpener can correct that edge to a true 20-degree.
e but must remove more metal.

With a new knife, I follow the 20-degree instructions BEFORE it seems dull. Each incremental sharpening requires only a few strokes and improves the already-good edge. I regularly find older knives that were lost in a drawer when they got dull. This sharpener does create a new edge but at a lot more strokes

5.0 out of 5 stars Wow! It's been ages since my knives have been so sharp.
Reviewed in Canada on June 13, 2023
So easy to use and works really well. My knives were shockingly dull. After reading a Consumers Report review, I decided this was worth getting. And after working my knives through five or six of the recommended sharpenings, I finally can slice paper cleanly. And the knives stay sharp - just an occasional touch up needed.

There are a couple of other reviews I recommend you read (especially one from Richard JS) - about how important it is to keep the knife upright while sharpening and do not wobble.

I was unsure if I should get this one or spring for the electric version. I am glad I picked this. It is very compact, fits inside my kitchen cabinet and was able to fix a very jagged knife that my wife wrecked. It took about 100 passes on the first level but it worked. Now it is as sharp as ever via the paper test. Very happy with this and I highly recommend it.
