How to Heat Treat 80CrV2 Knife Steel

I found no less than 4 different recommendations for how to heat treat 80CrV2, and nobody seems to know whose advice to follow. I compare the heat treatments, test the resulting properties, and give my recommendation on how to heat treat it for different situations including with a forge vs a furnace, and for stock removal makers vs forging bladesmiths. And I compare the properties of 80CrV2 to other steels and explain how it is different than the slightly simpler 1080 steel.
