## Customer Reviews

### ⭐⭐⭐⭐⭐ The $8 Reed Geek
*by M***N on May 13, 2022*

I purchased this instead of buying an $80 reed geek to adjust my saxophone reeds. The size and shape of this is almost identical to the reed geek and it performs just as well.

### ⭐⭐⭐⭐⭐ Cutting tool blank
*by J***R on October 21, 2018*

Cutting tool blank not a lot can be said about it. Positively what it says it us.

### ⭐⭐⭐⭐ Great for adjusting saxophone reeds.
*by C***Y on November 28, 2021*

I bought this because I didn’t want to shell out $40 for a ReedGeek to make some improvements to my reeds. This works perfectly well, despite not being designed for that.
