### ⭐⭐⭐⭐ 







  
  
    You have to put oil on it
  

*by R***N on Reviewed in the United States on January 1, 2022*

The screws are really tight when you get it but it works as a comb well :)

### ⭐⭐⭐⭐⭐ 







  
  
    Wow...
  

*by T***O on Reviewed in the United States on July 2, 2020*

This trainer is great. In two days, I managed to be able to open and close in a normal fast manner. It also functional thanks to the add on of the comb. The material is all metal, so durability is strong. Compared to others similar to this, this was the cheapest option I found and the best thing I did. Thanks to this, I’m now experimenting show off tricks for me to master before potentially getting a butterfly knife. Great product overall.

### ⭐⭐⭐⭐

*by B***E on Reviewed in the United States on May 30, 2020*

It was a little hard to get open and to relive.  But it is a great trainer and solidly built
