Handy small stone

### ⭐⭐⭐⭐ sharping for my clipers
*by C***S on April 2, 2023*

I used this to sharpen my clipers blades

### ⭐⭐⭐⭐ It does in fact work
*by E***E on October 2, 2022*

The grit is correct, and it does its job. It doesn't wear fast which is good. The 2 sides were adjoined terribly, and when I dropped it, the 800 grit broke in 2.
