HRC Rockwell Test - DIY Hardness Test

HRC Rockwell Test - DIY Hardness Test
Usually, harder steel increases the likelihood that blade will remain sharp for a longer period of time. Steel hardness is measured by the Rockwell C Scale or HRC. Scratch testing is a method you can administer yourself with a kit that contains six files. The files range in hardness from 40 HRC to 65 HRC. In this video I will show you how to test the hardness using the scratch method yourself.
