"I received this gift for Christmas. I like the adjustable magnetic base, but it does swivel a small bit when rolling the sharpener. It definitely sharpened the few knives I tried it on. I wish the adjustable base was more stable, but the swivel aspect makes that difficult. I also wish it came with 3000, 6000 grit discs and a strop for more refined sharpening. It's definitely good for someone who doesn't know how to properly use a whetstone."

Needed a knife sharper for a Japanese knife I got as gift recently and didn’t want to get a whetstone so once I saw a video of a rolling sharper I decided to get one of them. And picked this one over the others and I’m super happy with it! The sharpener is so easy to use, it’s high quality and works really well. My knives feel just as sharp now as factory.carmine mancini

The build quality feels solid and premium, and the magnetic base holds the knife securely during sharpening. After using it, my kitchen knives are noticeably sharper and perform much better when cutting. It’s efficient and much less intimidating than traditional whetstones.Overall, A great tool for home cooks who want sharp knives without a complicated process.jahir lara

This sharpener will wake up your dull knives! In just a few steps, it makes them like new again, and it won't slip thanks to the comfortable handle. It's compact, durable, and delivers exactly what it promises. Highly recommended!mark

discs do not last! This sharpener worked great on the first couple of knives then the abrasives on the disk were gone. I have good quality knives that I keep in good shape so I wanted a sharpener that would put a fine edge on them without a lot of work. I saw this design and liked it. You can find these at prices from $20. to $200. I choose this as a good middle of the road price point. Like I said the unit works good but you better be ready to shell a lot of money for replacement heads!What Customers Talk About
