I'm not sure I understand the responses. I've only got 2 razors so far, a 5/8 and a 6/8, both full hollows. The way I understood it, a shave ready edge is a shave ready edge, so the difference between a half hollow and a full hollow is just the weight and the "flex" of the blade. And the "song". Is that not right? I guess I'll just have to buy a half hollow razor now. In the name of research, of coarse.........
