### ⭐ 







  
  
    I can scrape the “diamonds” off with my fingernail!
  

*by T***H on Reviewed in the United States 🇺🇸 on January 26, 2022*

Is this some kind of joke? File vs my fingernail… fingernail wins. I can literally scrape all the little abrasive bits off with my thumbnail. That’s wrong. Do not buy.

### ⭐⭐⭐⭐ 







  
  
    Four Stars
  

*by J***Y on Reviewed in the United States 🇺🇸 on March 21, 2018*

Does the job when tuning my snowboard.  Make sure to wet it with water before/while using it.

### ⭐⭐ 







  
  
    Wears out quickly.
  

*by R***L on Reviewed in the United States 🇺🇸 on March 4, 2018*

Worked ok although the diamond coating started wearing off after the first set of skis. Have another DMT sharpener for knives, and have been very happy with it, this one not quite as much.
