Review on 🧲 Advanced Hardness Testing File Set by Jerry Frey

Revainrating 4 out of 5

A simple and fairly cheap way to test hardness.

A simple and relatively inexpensive way to test the hardness of metals without the use of expensive equipment. Make sure you always start with the hardest file and work your way up to softer files as you test. Otherwise, you can wear out softer files on hard materials. Great set to test.

Pros
  • Testing, measuring and testing
Cons
  • Not sure
