## Customer Reviews

### ⭐⭐⭐⭐⭐ Good, solid saw.
*by W***G on May 1, 2015*

This is a very high quality hacksaw. I finally got fed up with the el cheapos sold and wally world and elsewhere and decided to see if Starrett quality was still high. It is a very solid built and heavy saw. I was disappointed to see it was made in China. But what isn't these days?

### ⭐⭐⭐⭐⭐ Yes!
*by M***N on August 6, 2014*

This is a great hacksaw... balanced, very well thought out: the blade is nearly impossible to bend in the frame. Starrett Blades are also some of the best available.

### ⭐⭐⭐⭐ Nice design.
*by M***S on May 12, 2016*

Great hacksaw with a nice rigid frame and a crank mechanism which makes it very easy to adjust the tension on the blade.
