## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product
*by B***Y on December 1, 2025*

One is the best hining tools on the market. It leaves a knifes edge almost razor-sharp. I would highly recommend this item.

### ⭐⭐⭐⭐⭐ It's very sharp out of the box.
*by R***O on October 29, 2025*

It's smaller than other sharpener but it's perfect for my shorter knives.

### ⭐⭐⭐⭐ Not bad. Could be better.
*by A***N on January 26, 2025*

It actually works well for getting an edge back on a dull knife. Be very careful with your sharpening angle, though. This thing takes off more material than one might think. Great for garden shears, etc as well. I've found a few laps or more with a ceramic rod after really finishes off the blade beautifully. It's definitely not the only sharpener you need, but rather just one tool in the box.
