Chef’sChoice Electric Knife Sharpeners with Rechargeable Battery for 20-Degree Straight and Serrated Knives using 100-Percent Diamond Abrasives, 3-Stage, Gray

Highly recommend!! Very durable!!

I bought this product just over 6 month ago. I bought this model specifically because it has a rechargeable battery and doesn't need to be plugged in when using it. The battery stopped charging properly. It would show fully charged according to the light, then die after 30 seconds of use. I contacted them, even sending a short video of it plugged in and fully charged, then running out of battery quickly. Their response was instructions on how to charge it - really? When I responded that the video showed that's what I was doing, then zip, no response. Shocking support on a warranty issue

Easy to use and creates a perfect edge on my German knife.

Before I start, I want to say shame on me. Re: later. On march 17, 2024 I ordered a chef's SCH22. Loved it until sept 24. At that time it failed to hold a charge and only worked if connected to outlet. Ok, so I received a defective one. On Oct 17,2024 I ordered a chef's choice SCH32. Different model. Received it opened box unit DOA. Wouldn't charge wouldn't even turn on plugged in. Now here is the shame on me comes in. Sent it back and opted for a replacement instead of refund. Received replacement and works great, until the first of Mar 2025. Same problems as the first one I purchased. I would not recommend this one if it were the only one on the market. Today I have purchased a different brand and will see what happens next. Good luck if you purchase chef's choice. Hope you have better luck than I had.

Wow. This sharpener is AWESOME. It scared the life out of me at first with the sound but it’s really an awesome tool to have. I have some really expensive knives I never had work on from when I was working in restaurants. Couldn’t even cut an onion. I didn’t throw them away because I knew at some point I’d fix them up. I put them on this sharpener and they’re good as new. Back to cutting like a dream. Highly recommend. I did all of our normal home knives also. Makes me feel safer knowing I’m working with sharp tools again and it also makes me feel better that other people in the house are working with sharp tools. Dull tools cause more accidents and worse injuries because you’re using more force to try to get the job done.Everyone needs one of these.

The only downside: this is a bit bulkier than I'd expected or, frankly, wanted, which is a consideration if you have a small kitchen where adding even one more gadget is a squeeze. That said, it has plenty of upsides, too.-- Clear instruction manual-- Quick sharpening time compared to a conventional sharpener-- Easier to use than a whetstone or sharpening steel (for me, at least; YMMV)The bulk does have at least one upside: it helps the unit stay put while you're sharpening. Not a bad investment, especially given the cost to pay someone to sharpen your dull knives.

I tried several USB-C chargers - didn't work. Their proprietary charger is the only one that works per the instructions (see below). So evidently one of the advertised features is really a scam. Not a good start.From the instructions:Use only with Listed/Certified ITE Power Supply. Do not use an extension cord. Plug charger directly into electrical outlet. Use only with the charger provided with the appliance. Do not attempt to use this charger with any other product. Likewise, do not attempt to charge this appliance with any other charger.

My son is the chef in the family and when I showed him this electric knife sharpener he went right to work on my knives. This unit is awesome! He found that this unit works great! It will save him a lot of time and make life a lot easier for his work. I highly recommend this electric knife sharpener. It would make a perfect gift for your chef too!
