I’ve been rotating razors the past few weeks using a new to me Kai blade. The Gillette NewDeluxe still gives me the best shave . The Karve CB , Gillette New short comb and Merkur slant come close and it’s hard to differentiate between them after the shave but 24 hours later I have the same amount of stubble with the NewDeluxe that I have after 10 hours with the others
