I was watching a show yesterday, Modern Marvels, and it was all about sharpening. Showed all kinds of awesome computer graphics and discussed edge grinds, heat treat, and sharpening tools.

I saw a barber using a smooth combo stone to sharpen his straight razor, brown on one side and black on the other. (He used water on it). He then used a canvas/leather barber strop to finalize his work. I want a stone like this! It was more square than rectangular. Anyone know where I can find one? I have searched the web to no avail.
