I am using a 1940's vintage Gillette Super Speed double edged safety razor. I have another Gillette Super Speed from 1967. I bought the razors for about $12 including shipping on Ebay.
My brush is a Boar bristle of unknown make that was given to me by a generous member of a forum I belong to.
I bought a stand for my razor and brush for $40. For my Col Conk's soap I use a small wooden bowl I found in the pantry, and lather up in a cappucino mug I picked up at Target for $4.
Some C.O. Bigelow (aka Prorasso) shave cream cost me $10, a can of Prorasso cost me $9, and I was given a puck of Col Conk's Bay Rum shave soap.
I ordered a sampler pack of razor blades, too numerous to list here. I will name them off as I use them. The cost was around $30.
And of course the scents and skin care:
Clubman Bay Rum. Very inexpensive and smells like an old fashioned barber shop.
Art of Shaving Peppermint Face Wash. Awesomesauce.
Art of Shaving toner. Unscented, good for the skin. Tightens the pores.
Art of Shaving After Shave Balm, Sandalwood. One of my favorite scents and a fantastic after shave. Very soothing.
Lucky Tiger Moisturizer. Old school goodness.
Michael Jordan cologne. Smells as good as he plays.
Once a week I use french green clay mask to clean my face thoroughly. Its inexpensive and very effective.
So I'm off and shaving. Bear in mind that I have several soaps and blades to experiment with. Once I figure out what works best for me I'll cut the recurring costs down substantially. Especially when the occasional after shave or brush pops up for a birthday or Christmas ;)
