### ⭐⭐⭐⭐⭐ Great for Practice
*by A***A on March 17, 2026*

Great quality and ease for practice.

### ⭐⭐⭐⭐⭐ NOT sharp at all.
*by J***E on April 8, 2026*

Buying this for my grandson to practice with. It is very good quality and the opposite of sharp.

### ⭐⭐⭐⭐ Great product, worth the price!
*by A***Y on August 22, 2025*

When I first got it, the joints were a little bit stiff on one side, but after enough flipping, it does loosen up. The build quality is really nice, and the design is nice and tactile. The flipping works perfectly, and the blade is completely dull, so it is perfectly safe for practice. It functions perfectly, and for the price, it is definitely a steal!
