Hi Prince,
From what I hear, it should be a fine knife. I believe it was David Boye who invented dendritic steel. If he didn't invent it, he sure was the frontrunner for developing it for use in knives. Anyway, he develped it because of it's abilities to cut rope efficiently and keep cutting it. His father was a coastal fisherman and lost his legs due to an accident involving rope - an accident that could have been prevented had he been carrying a knife. David focused much of his life making knives for coastal fisherman so they will always have a knife ready in an emergency - interesting story. Anyway, that's the flagship steel of his knifeshop now. Should do just fine on deer.

BTW - Where do you hunt blacktail deer? From the pictures I've seen, they look like a very stocky deer. I'll have to try a blacktail hunt one of these days....
