I would say you are right. However, I found that when I paid attention to using a consistent angle of well more than 45 degrees the results got better and lasted longer. However, the results still wouldn't last as long as with the best of my razors, mainly injectors with NOS blades. However, the shaves I had with the AS-D2 were so enjoyable that I can overlook this minor detail. I'd happily have it as one of my regular razors, but not as the only one. I can't think of any razor I'd use exclusively..It does tame the feather blade quite well judging by the shave this morning.
I would say although a nice and easy close shave, the stubble has grown back quicker than with previous DEs?
Isn't it beautiful though? Did I mention that I like this razor?
