Regarding the comparison between the Blackbird and Athena. I can express my opinion firsthand, because I have two Athena bronze and Ti, as well as the Blackbird SS. Definitely, the way these razors shave is fundamentally different, but the end result is very similar. I can get a perfect BBS from each, but with Athena it happens much easier and most importantly, pleasantly, just relaxing autopilot.
This does not mean that the Blackbird is a bad razor, quite the opposite. The rough feeling can be significantly reduced when the right angle is found, and it is shallow. If you try to shave at a steep angle, there is a high probability that you will not like it. Because the protective strip steals the soap and the blade goes almost dry.
However, given that there are two Athena and I am not selling either one, you can probably guess that I prefer Athena to Blackbird
