If you want to "feel" the difference then take a blade that is HRc 58 and one that is HRc 60/61 and try to file the edge. I have tried to file 154cm at HRc 60, using a new Nicolson or simmons file and it just makes a "zinging" sound and does not remove hardly any metal but at HRc 58 the file will remove metal much easier. highlander recall 2020 https://alistsecurityinc.com
