Straight or Serrated Blades

Not only does it restore blades in seconds, this versatile, electric sharpener is designed to sharpen both straight edge and serrated knives.

Diamond Abrasives

It also features 100% diamond abrasives for long product life. With these more durable abrasives, you can be sure the unit will last longer, even when used frequently.

Precision Guide

Boasting a helpful precision guide, this sharpener helps keep knives in the ideal position to achieve the best results and sharpest edge.

3 Stage Sharpening

This electric sharpener has a 3 stage sharpening process that ensures a pinpoint, like-new edge each time. Stage one is generally used for knives that are extremely dull or have not been sharpened in a long time. For just maintaining a knife and putting a quick edge back on, stage two is ideal. Stage three is the strapping stage which takes off any burrs for a smooth, razor sharp edge.

Easy to Clean Out

This model can easily be cleaned by pulling out the cartridge and wiping off the magnet that collects blade shavings.

Small, Compact Design

Its sleek and durable exterior complements any kitchen's decor and its small size allows it to fit on countertops for easy access.

Customer Q&AAsk a Question

Can this knife be washed in a dishwasher?
No, hand washing with soapy water and sanitizer solution is always recommended. When placed in a dishwasher, the process will often rust and cause damage to the edges of the blade.

Customer Reviews


Great product. I used to have a company come every two week and have to pay them $35 each time to sharpen 7 knives. Now I just run the through this machine a couple times and good to go. I had it for a couple of years and no complaints yet.

Tom M. from Doylestown Deli on 04/06/2022

Love this item. Got it to sharpen kitchen knives and it works super well, easy to operate and efficient. Fast. Would highly recommend to anyone.

Juanita F. from Angel's With Furry Souls on 12/24/2021

This was very easy to use and the directions simple to follow. It kept the knives sharp. We used it weekly or monthly depending on how much we used the knives.

Heather D. from Greene County Schools on 12/19/2021

Mercer knife sharpener is well worth the investment. Restores a knifes edge to better than factory. I would highly recommend this product.

Kenneth I. from Gracies on 03/16/2021

I just received this machine today. I was so excited to use it. I was happy to find that the machine is ready to use right out of the box - just plug and sharpen. I used the sharpener on a couple serrated edges and one flat edge. All of the blades are remarkably sharper. I cannot speak to the longevity of the machine or how it holds up, but my first impressions are great.

Charles J. from Atlantic City Sub Shops on 02/21/2021

This is OK. I have it and still use it even though it kind of damages the sides of my knives. For the price I do regret not just getting whetstones and learning how to get what would end up being a sharper edge but this is convenient so I'm willing to pay the price. The rubber guides are sometimes hard to figure out how to engage the sharpening on the heel of the blade at times and I've noticed after long-term usage that I'm cutting into the rubber a but as I pull but it doesn't seem to affect performance at all.

Phi D. on 04/25/2020

this electric knife sharpener is doing its job perfectly, since i bought my life is easier at the kitchen no more wasting time or destroyed tomatoes

Gumercinda S. from Sabor Peruano on 01/06/2020

Nothing worse or more dangerous than trying to cut things with a dull knife! Simple to use and keeps our knives in much better shape. Not the best unit out there but its simplicity and price make it a great option for the average kitchen.

Justin M. from Aulac Big Stop on 12/18/2019

I have to sharpen a lot of knives and i could not imagine doing it by hand. this machine has been a life saver and brings a really nice edge to my knives.

Michael W. on 03/24/2019

So far so good, we started buying our own knives last year and haven't looked back, i expected more from this sharpener but i'm sure i'll get better as time goes by, not quite as sharp as Cozzini but i'm getting there.

Andrew M. from La Gondola Chicago on 01/08/2019

I have used this unit for over a year now and this sharpener works great. I sharpen my knives every two weeks (or more if the help roughs them up) and it keeps a good edge on even my cheap knives. Much safer than dull knives and injured employees.

Virgil P. from PETRI's POUR HOUSE INC on 06/19/2018

I had a bunch of kitchen knives that were badly beaten up and dull. This let me sharpen ten or so cheap knives in like 20 minutes, and gave them a good edge.

Nicolas A. from La Fonda Inc on 02/21/2018

I love this electric knife sharpener. It's so easy to use and it's faster than sharpening it by hand. You can also sharpen three knifes at once

Lalit P. from Foxland Market on 09/07/2017

This sharpener is excellent. It pairs especially well with the entire set of mercer millennia knives we purchased. The sharpener is extremely easy to use and leaves a razor sharp edge on the blades. The only downside is the small magnet it uses for catching the metal shards needs to be cleaned often.

Yitzchok W. from Shinanta Inc. on 07/04/2017

With this product, you will never have to send your knives out to be sharpened again. It will save you a lot of money in the long run. It keeps your knives sharpened for weeks on end with high usage.

Sara H. on 06/29/2017

I have always outsourced our knife sharpening, but never again! This unit is so easy to use and really does a great job of getting even the really dull knives super sharp!

Julie F. from Julie's Deli on 02/06/2017

Really easy to use. I love how sharp it makes my knives and how long they stay sharp. It is electric so it makes it easy to use

Diana T. on 12/15/2016

We are very happy with the Mercer M10000 Triple Diamond 3 Stage knife sharpener. It does a great job and speeds up efficiency and beats using a manual sharpener.

Guillermo C. on 11/17/2016

F fantastic I love it this thing sharpens knife like a razor blade. Kind of expensive but well worth it. Even sharpens serrated knife blade

Mike R. from Home on 11/09/2016

We replaced a different brand with this knife sharpener and we are very happy with the ease of use and the sharpness of our knives. It is everything we expected and will purchase more for our other restaurants.

Chris B. from Freebirds World Burrito on 04/24/2015

This is something I should have bought years ago. Sharpens all knives perfectly. I have expensive knives I quit using because they were so dull. This sharpener has brought them back to life!
