I have spoken to Charles on the phone back when I was shopping Simpson brushes. He is a very nice, VERY talkative guy (75 pages :)), and quite intelligent on all aspects of shaving. He'll try to convert you to the "method" that's for sure. From our conversation, this is what I gathered....the cube is a big 3" cube of some sort of shaving soap. Supposedly it doesn't smell very pleasant either. The gist of it is you bash the hell out of your wet brush on the cube to "load" it. Then you take it to a cream (cutting balm maybe?), and after the shave is done, he has a few post shave steps to be used with his products. Toning, aftershave, balm, etc. The method isn't so much a different way to actually make passes, but rather the whole approach to shaving. Mostly with the lather building and conditioning I think. But I'm probably off a bit. Go to enchante, get his number and call him. He'd be ECSTATIC to give you the run down. Just don't call him when you need to be somewhere in an hour.
