For what it's worth, I think 80CrV2 steel is quite a bit superior to 5160 in almost all regards. Not that 5160 isn't a good steel. But I think 80CrV2 wins in toughness and edge holding. It's been called 1080+ in the past, but looking at the chemical makeup, it doesn't really heat treat the same as 1080, or rather, if you do heat treat it like 1080, you might be leaving something on the table as far as performance. I'd compare it more to 5160 with a lot more carbon and a bit of vanadium added.
It is an incredibly tough, incredibly fine grained steel that has excellent edge retention and capable of excellent edge stability even at high hardness and with really thin grinds.
