Until Mrs. Chandler requested that I grow a beard, I shaved for years with (sharp as $%^&) Parker blades in a beautiful Merkur Futur knockoff.
I discovered, however, that the real secret to a good shave is Cremo shave cream.
I use an English shaving soap that is excellent.
Edwin Jagger sandalwood shaving soap. It is good stuff.
