Merkur with Derby blades
I have a badger brush and soap from Art of Shaving that I use on special occasions or when I have a lot of time. Typically use Nivea balm before going with the grain, and again before going against the grain. Been doing this for 3-4 years. Recently on a trip, TSA took my blade away so I bought a Mach 3 at CVS. It really didn't do nearly as good of a job even after with and against grain, and I got some burn/bumps on my neck.
I shave 3x week, unless stubble isn't appropriate for my weekend plans. Blades last a week then get tossed. Could possibly last longer, but they're so cheap, who cares?
