Three observations:
Judging from photos on B&B, there are two different physical designs (shapes) not just two types of steel.
I have the one with no gap between the plate and the cap. It gives a moderately aggressive shave. Just a bit too harsh for me, so I rarely use it.
The Darwin is probably the most beautiful razor ever made but, somewhat surprisingly, is not all that comfortable to hold. Somehow, the bumps and hollows do not quite produce a shape that is easy to grasp.
