Testing the diamond sharpened edge: I sharpened the original blade that was at 600grit AO fine India to 600grit fine diamond . This cut 380 and began skating 'some' at 450 more and I stopped at 525 cuts . Plus, upon examination this one expressed less burring . So, I'd say the diamond sharpened blade will cut more rope . At least at 600grit . The summary: the 100grit sharpened blade cut 1100, the 280grit cut 375(maybe 400), the 600grit India cut 200, the same grit diamond cut 525, the 1000grit Arkansas cut 200 and the 2000grit ceramic cut 400 . Trying to make sense of this test I'd say grit matters as well as the grit type (diamond) espically the bitey grits . Then the grit size (larger) relates to increased edge retention . The refined edges have a place as well in quick cutting using little effort . ie. shaving or hospital operations . Choose carefully between how much edge refinement is required and how much edge retention is needed for your cutting . Now, I'm out of rope . DM
