My Blackland Dart is my favorite razor to date. I consistently get 2 pass BBS shaves without any nicks, cuts or irritation. It is not the only razor I use, nor the only one that delivers a 2 pass BBS shave, but it is the one I reach for most often. Of course, I should just stop there, but lately I've been tempted by the Blackbird, particularly as I've seen some pop up on the BST. For those who have used both, how would you compare the two?
