There's a reason gentlemen lathered their leather with fancy brushes for centuries before the dawn of the Gillette Era - it works. The science is very simple: shaving brushes allow your shaving product to better penetrate the beard stubble by getting underneath the stubble, while also making stubborn gristle stand up at the same time. The result is a supremely comfortable and dapper close shave. And despite widespread misconception, brushes are supposed to be used even with the modern, manual/electronic, multi-bladed behemoth slicers. In all truth, once you lather with a badger, using your hands to apply it will feel decidedly brutish. (Shown: Edwin Jagger Badger Shaver Brush, Metal Case).
