Product Description
This compact 3-stage electric knife sharpener for kitchen knives comes equipped with 100-percent diamond abrasives that sharpen edges faster and easier. Ideal for all 15- and 20-degree knives, including both straight-edge and serrated knives, this sharpener improves cutting performance by creating 2 distinct facets set at different angles to form a longer lasting, arch-shaped edge. The first stage sharpens 15-degree knives, while the second stage sharpens 20-degree knives. In the final stage, patented stropping disks apply an unparalleled polished finish to both 15-degree and 20-degree knives. The Chef’sChoice 1520 quickly and easily sharpens virtually all quality cutlery, including American, European, and Asian-style household knives, fine-edge or serrated blades, Santoku and traditional Japanese-style single-bevel edges, as well as sports knives and pocket knives. Advanced patented technology restores and recreates 20-degree edges for traditional European- and American-style knives and 15-degree edges for Asian-style knives and contemporary European/American-style knives. First-time sharpening takes approximately 1 minute. Resharpening takes approximately 10 seconds. Precision angle guides ensure accurate sharpening throughout the entire blade length and eliminate any guesswork.

- Reviewed in the United States on October 12, 2024Color: WhitePattern Name: Chef'sChoiceVerified PurchaseI'm very pleased with this sharpener. I was debating between this one (model 1520) which is a 2-stage system that can sharpen at 15 or 20 degrees, and the Trizor model, which is a 3-stage but can only sharpen at a 15 degree angle. I went with this since some of my knives are better suited for a 20 degree angle (plus the fact that it was on sale for 50% off, making it less expensive than the Trizor).
Usage is about as simple as it can be, and the guides ensure the knife is held at the correct angle. The instruction booklet provides detailed instructions on how to use it for a variety of different knives, and how to maintain the sharpener (which is pretty easy).
Operating sounds when a knife is not being pulled through are limited to a low hum. It does make a fair amount of noise while sharpening, but that's to be expected from any sharpener. The machine has a nice, solid heft to it.
The results have been outstanding. I'm sure hand sharpening with a whetstone would be even better, but since I don't have the knowledge on how to do that properly (nor am I willing to spend the time learning) this hits the mark for me: easy to use, and the end result is a scary sharp knife.
You can also use this to create a three-bevel (Chef's Choice calls it a "Trizor") blade by starting with the 15 degree slot and then using the 20 degree slot for just a quick pass before final honing in the third slot. Instructions are provided in the manual. I tried it, but didn't find there to be much difference in sharpness compared with just a plain 15 degree sharpening. But, it's nice that the option is available for those who want to use it or experiment.
An excellent, easy to use sharpener that produces great results. Five stars.
- Reviewed in the United States on February 28, 2025Color: WhitePattern Name: Chef'sChoiceVerified PurchaseBought this to replace a similar Chef's Choice that had been in the family for 32 years and had finally developed bearing noise when running and was obviously about to go. It was an expensive splurge then and an expensive splurge now, but worth it. Over the decades this device has been refined and this new one works so much better, with fewer steps, 15 degree support, and brand new sharp cutting wheels! The only thing I miss from the old one was the magnetic blade guides which the knife angle. This one uses a spring tensioner. Not as elegant or easy to use, but works fine and doesn't magnetize your knives either I guess.
- Reviewed in the United States on December 18, 2024Color: WhitePattern Name: Chef'sChoiceVerified PurchaseInstructions were easy to follow and it took me only a couple of passes to master the technique which is very simple. If you follow the instructions you will have extremely sharp knives. I tried an expensive Torek system but that required so much more skill and time and mess, then I tried a Lansky manual system which worked pretty well but very time consuming moving from stone to stone. This Chef's Choice was very fast and I got incredible results on the first try. Better than any sharpener I have ever used. I sharpened all our kitchen knives in record time. I took 4-5 passes with each knife and did the same with the stropping wheel. I sharpened 9 knives including 2 serrated. They are all as sharp as when they were new. Don't forget to clean the metal waste magnet on the bottom. I removed it and cleaned it with an old tooth brush. I was amazed at the amount of metal shavings after 9 knives. I never mastered the art of sharpening knives but this machine requires very little skill for dummies like me to get extremely great results. Wish I had found Chef's Choice years ago. Would have saved me a lot of frustration. Definitely worth the $.
- Reviewed in the United States on July 26, 2014Color: GrayPattern Name: Chef'sChoiceVerified PurchaseReceived this July 24th 2014. Couldn't wait to test out the 1520 on some of my knives of yesteryear. I have knives from graduate school, when I was a young pup, which could have been used as spoons- very glad I hung on to them. I have a Chicago cutlery 7 inch knife that was in this category and is now almost as good as my Global G-46 (oh! And btw if you want a knife that is truly outstanding and will be squabbled over by your heirs it is the G-46 - another review for later!)
The 1520 worked wonders on the knives that I sharpened. Took about 30 minutes for 8 knives (after I had read through the instruction manual). I started out by trying to cut a piece of printer/copier paper - the Global G-46 knife which is about a year old and the massive Lamson-Goodnow knife were able to cut the paper. I also used a plum (no tomatoes). Only the G-46 was able to cut the thinnest slice off the plum. A couple of others could cut thicker slices and some couldn't cut through a plum without crushing it significantly! The goal with a very sharp knife is to get me a slice off a plum (or tomato) that is thinner than a sheet of paper. At the end of this first foray into knife sharpening every single knife I sharpened with the 1520 could cut the perfect slice off a plum.
A very good product with a minor issue! More about this at the bottom
The device is "assembled in U.S.A". Not sure if that is a euphemism for packaged in a box here in the states! Comes with a 3 year warranty
A couple of provisos: you CANNOT sharpen ceramic knives or scissors with this.
The instruction manual is well written and lucid - a rarity in our age. It may be available on their website (can't link to one for you - amazon deletes the link!).
There are six grooves, in three groups, that are available for sharpening knives. The first group is for Asian knives (like the Global G-46). The second is for American and European knives. The last group is for the final honing and polishing after you are done with group 1 or group 2.
Each group has two grooves. Think of each groove as a v shaped piece of plastic you put your knife into and pull through. Most knives have a left side of the blade and a right side. You alternate between the groove, first pulling through the left groove and then the right, within each group.
I took the Chicago cutlery knife (mentioned earlier) and decided to try and convert it into an Asian blade (If you look at a knife as you are cutting something, the very top of the blade is blunt and thick, the sharp edge forms the bottom and tapers. The taper is 15 degrees for most Asian knives. American and European knives have a 20 degree taper. Asian blades tend to be sharper but thinner because of the difference in the taper.) In about 5 minutes it was razor sharp and now had the 15 degree taper. I was frankly very surprised that I got the perfect edge where none had existed for over 14 years.
A negative: The grooves are plastic and I found that by the time the knives were on the honing wheel they were cutting into the plastic that forms the wall of the grooves. The actual sharpening occurs in the valley of the groove and there is no plastic there. Still I had to be careful when inserting the knives into the grooves so as not to keep cutting the plastic as I pulled it through.
You may want to do a search for Chef's choice 115 as well - not sure if it offers the two different knife type options (Asian & European).

5.0 out of 5 stars Fácil de usar y resultados perfectos
Color: WhitePattern Name: Chef'sChoiceVerified PurchaseEs lo que anuncian salvo en dos aspectos. Viene con clavija inglesa y las instrucciones no vienen en español.
Una vez que consigues hacerlo funcionar, con un adaptador o cambiando la clavija e interpretando las instrucciones y viendo algún vídeo por internet, ya puedes proceder a el afilado.
Es importante ver/leer antes las instrucciones. Ya que habrá que usar la ranura 1 o 2, dependiendo del tipo de cuchillo. No es como otros modelos que hay que pasar por las tres ranuras.
En este caso 1 + 3 ó 2 + 3
El resultado es perfecto. El cuchillo una vez afilado es casi un bisturí. Haces la prueba de cortar un folio y te quedas boquiabierto.
Es un producto caro; pero deja los cuchillos cortando como nuevos.

5.0 out of 5 stars Feines Produkt
Color: WhitePattern Name: Chef'sChoiceVerified PurchaseWar erst etwas skeptisch, eines meiner Damast-Messer (235,00 EUR) damit zu schleifen (bisher immer auf verschiedenen Schleifsteinen). Dieser Schleifer hat zwei unterschiedliche Schleifwinkel - für europäischen und asiatischen Schliff) Zunächst habe ich mit alten Messern angefangen und probiert. Keines der Messer wurde beschädigt, alle wurden wieder scharf! Dann meine Damast-Messer. Etwas Übung, etwas Zeit und das Ergebnis ist super. Beim ersten Schliff je Messer innerhalb von max. 5 Minuten ein echt scharfes Ergebnis. Ein erneutes Nachschärfen geschieht in weniger als 1 Minute pro Messer! Klare Kaufempfehlung.

5.0 out of 5 stars Japanese and American knives sharpen well
Color: WhitePattern Name: Chef'sChoiceVerified PurchaseI have both Japanese and American knives. It does a great job on both, because it has two separate sharpeners one for Japanese at a 15 degree angle and one for US at 20 degrees. When using the sharpened Japanese knives be very careful, as the edge becomes razor-sharp. My wife already cut herself, as it was never that sharp before. Makes it worth paying $200 for a true Japanese knife. Don't use the Japanese edge for cleaver-type cutting, but softer things like veggies. The 20 degree American edge is good for heavy duty meats, chicken with bones, etc. I sharpen much more frequently now as needed, rather than the hand sharpener. I procrastinated on that boring task, letting knives get dull. With this I sharpen frequently and easily.
