I thought I might add a few observations I made in last month's focus. The obvious observation is the head geometry. The Fatboy head is definitely taller than the other two. On the surface, the Slim and Black Beauty have the same geometry. Here is the photo (I will apologize ahead of time, as I don't have a macro lense):

When looking at the blade angle on dial setting one, all three razors look somewhat similar.

When I moved the dial to position 9, though, more of a difference appears. The Fatboy and Slim both seem to hold the same angle, but the Black Beauty seems to flatten the blade out some. Admittedly, the difference is more noticeable in real life than these pictures.

When using these razors, it did feel as if the Black Beauty got a bit more aggressive than the other two when the dial increased. This slight change in the blade angle would explain this.
Both the Slim and Black Beauty have a bit more blade exposure on 9 than the Fatboy.
All in all, I enjoyed all three razors. The Black Beauty tended to fall a little short of the other two. If this was a 1975 (birth year) razor I would definitely keep it, but I will likely look at passing this razor on to someone else. I could see keeping both the Slim and Fatboy, so I will still need to think about these two. I greatly like how both razors shave, so it is tough.
