My perfect shave: Semogue 1305, Handmade Almond Soft Soap, and My Long Handled Mergress Loaded With A KAI Blade and Finishing With Boosters Iced Lime.
Not really dependent on a particular razor, blade, brush, or soap, or any particular combination. The perfect shave is most like to come when well rested, relaxed, and unhurried. A nice long shower first, no particular prep other than that. No post shave routine other than rinsing off. Followed by a cup of coffee, black.
