Continuing my week of bakelite razors, tonight's shave was with the Neillite 400. This was another razor that originated in Sheffield England made by James Neill & Co along with the Four Hundred Co based in New York around 1935. The razor was unusual because it had differential sides, with one side having closely separated scalloped guard, and the other side more widely separated. This actually did result in a milder shave (the side with more bumps), and a more aggressive shave (the side with less bumps). Personally, shaving with the milder side is probably like @efsk Merkur Progress on setting 0, however the more aggressive side was very efficient and not so rough. Sticking with the aggressive side for the shave resulted in a very efficient and comfortable shave.
