Review: High quality device to sharpen knives - I'm just an amateur home cook but every now and then I feel my knives getting dull. I usually take them to Sur La Table to be sharpened but was interested in being able to do it at home myself. I've purchased knife sharpeners before as gifts and they were less than impressive, so I was excited to try this Ultra-Edge Diamond and Electric Knife Sharpener from Mueller. I was worried that the base didn't have suctions or a crank stabilizer (found on apple corer devices), but the machine is designed with a safe place to put your hand while cutting, and I didn't find it to be moving during operation. The instructions are clear as to how to use the device, with both slots on the 1 and 2 side, as well as how many passes are required for each, depending on the dullness of the knife. The device does have a catch for the shavings and a safety in case it overheats. Everything is clearly stated in the instructions. After sharpening, I could see where the blade had been sharpened, and I tested it on tougher tomatoes, as that usually is a good determiner on how sharp a knife is (for me). If I have to really push and make a few passes before the knife breaks the skin, it's not sharp. If it cuts through easily, it is. Obviously I'm not a professional chef or blacksmith, but found this device to work well on my knives. I ran about 7 knives of varying sizes and brands through. Review: Hey, just get it! - I've used a few different tools for sharpening kitchen knives. And had little to no success with any of them. Hey, lousy tools do lousy work. This thing is motorized, but is no bigger than one of the non-motorized tools I bought. It took a little practice to put the knife in and keep it pressed against the guide. I still get it in wrong occasionally. But if I'm careful, and in no hurry, I now get some seriously sharp knives for the wife to use. Is a wonderful experience, to work in the kitchen with a truly sharp cutting tool. I'm sure other tools, with a lot more expense and more user expertise, can probably get a sharper edge. But this thing will be a revelation to someone who's never had a decent edge on a kitchen knife. Don't buy the cheaper junk that doesn't move the cutting edge for you, and relies on just the movement of the knife in the sharpener. Get this thing, and enjoy! ## Features - Expert Precision – A sharp knife is the most vital tool you need in your kitchen.

It is well made in many ways but does not have the power I need. It stalls out when under a bit of a load. It is ok for light sharpening applications but not if you want to do a number of knives in succession. There is a thermal override that turns the motor off to prevent overheating which occurs after only sharpening a few knives, you then have to wait for the motor to cool down before resuming. I only recommend this sharpener for those who may only want to do 3 or 4 knives at a time and have light sharpening needs. I now wish I would have bought a heavier duty sharpener. This is the first electric sharpener I have owned, up to now I used a sharpening stone by hand. I will try to use this for awhile longer and have to train myself of the need to go slow and only a few knives at a time. I did find out that the second sharpening was better than the first as the angle was better established on each knife. But still the motor override is a pain and irritating, the motor heats up way to fast. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/246932793-mueller-4-in-1-4-stage-best-knife-sharpeners-kitchen](https://www.desertcart.sn/products/246932793-mueller-4-in-1-4-stage-best-knife-sharpeners-kitchen) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-10-25*
