One more comment regarding the various Rockwell plates. Let me preface this by saying that I have never shaved with the Rockwell system, but I did purchase one for my son a couple of Christmases back soon after they launched the stainless version. My go to DE has for a long time been the ATT system, which only has 3 plates and 3 aggressiveness levels, M, R and H. These plates are available in open or closed comb. I opted for the open comb, and I have settled on the H2 plate which is their most aggressive. ATT sells their 5 piece set for $299, comes with your choice of handles, 3 plates and a cap. For $99.00, the Rockwell came with a handle, three plates with 6 aggressiveness options contained within, and a cap. For me it was sort of a no brainer. The Rockwell cost 1/3 the price of the ATT system, and provided twice the flexibility to find an aggressiveness that suites your beard/style. When getting back into DE shaving, the biggest challenge that I has was that I was not sure what aggressiveness level would suit me. Had the Rockwell system been available then, I certainly would have purchased it for myself. I am not equating the quality of manufacture between the ATT and Rockwell systems. ATT wins that battle hands down in my opinion. But the Rockwell system is well made, even if it does appear a little unorthodox due to the two sided bases.
My son is not a shave nut, and he probably only shaves once or twice a week. But, he does have a very full and thick beard. Previous to Rockwell, I had gifted him the Merkur Futur, which was his first experience with a DE. As stated above, I was not sure what aggressiveness to get when I came back to the DE, so I certainly could not make assumptions for my son. Once he shaved with the Futur, he has been a DE guy ever since. In his particular case, I think he likes it because it really is way more economical than cartridge shaving, and he gets better results. Especially since dad gave him the razors, and an Astra SP 100 pack. He texted me the other day and wanted to know if I had any soap, so one of the 4 oz. Beta 1.2.1 pucks has his name on it. I have no idea how long it will take him to go through the Astra blades, but I can tell you, the next 100 pack is on him.
