Achieving a good shave under the nose can be a tricky endeavor for many men, including me (and my Mediterranean nose)! The best safety razors I've found for getting under the nose include (in alphabetical order) the Blackland Vector, the Henson razor, the Leaf Twig and Thorn razors, the Parker Adjustable Injector razor, the Parker SoloEdge razor, the RazoRock Hawk razor, the RazoRock Lupo razor, and the Rex Ambassador adjustable razor.
