I recently discovered the spreadsheet linked below, which claims to show independent hardness test results, as well as steel analysis. Can anyone vouch for the accuracy of the data? https://docs.google.com/spreadsheets/d/1OepNr_D4lqbdTFqdqWl1rmAd4bOzPzJe6J0iEWrdJGU/edit#gid=0 If the analysis is correct, then Fura and Eefengrow, along with Kolour, Y-Start, and Komoran are not even made of the steel they claim to be made of. I see one Ganzo model that fails the steel analysis as well. Another question: how in the world do you sharpen Spyderco's Maxamet, if it is 69 HRC?
