    Very sharp and sturdy
  

*by J***H on Reviewed in the United States on 16 April 2024*

Really upped my 3D carving game and cut hours off some of my more detailed carvings.

### ⭐⭐⭐⭐⭐ 







  
  
    Good bit
  

*by J***X on Reviewed in the United States on 28 January 2023*

Just finished a 15 hour cut with one of these and it’s still making a nice clean cut. I guess that’s all I need to say.

Not as good of a cut as I expected.This is an OK product, but I was disappointed in the cutting ability a bit.  I expected a smoother cutting finish. Other than this, good buy, money is right.
