The Knives used were Spyderco Endura 4 FFG and Benchmade 710-1.
Material was 1/2" Manila rope.
ZDP was tested 1st and I cut until it would not cut paper without tearing it.
Results
ZDP-189 = 550
M390 = 600+ (I stopped after 600)
Impressions
ZDP did extremely well until around 450 cuts then it noticeably harder to make the cuts as in it got to be a lot of work. After 550 cuts it started to tear paper.
M390 even after 550 cuts it was still not getting noticeably harder to cut the rope, after 600 cuts it was still pretty easy and it would still slice paper clean.
Nothing is conclusive or the final word etc on this as this is just my informal findings between these 2 steels. Both are excellent and hold an edge for a very long time, both are at the top of the heap IMO of the Super Steels.
