The actual Rockwell averaged 61-62. We choose the lower Rockwell on this project due to the toughness loss at the higher hardness. For our product customers, it makes more sense. The tip breaking on the 110s is one of our top returns and we know people pry with our blades (gasp! lol), so we wanted the toughness. Plus it is easier to re-sharpen etc.
We have just adopted a new sharpening method that has raised our CATRA scores significantly for initial sharpness/total life, so edge life should still be there at the lower Hardness.
Hope this helps.
