This is Rockwell's 2-Piece Razor manufactured in Stainless Steel.
These were announced and released in late September 2026. I ordered this and the Aluminium Version and they took about two weeks to get to me.
The adjustment mechanism is based on that of the Merkur Progress but unlike the Progress, they moved the adjuster dial to the top. This has the added benefit in that the topcap does not have to be lined up.

How does it shave?

First shave in - It's an excellent shaver. I think that "setting for setting" its slightly less aggressive than the Aluminium Version. I ended up with a great shave but it took end to use a bit a little bit more to get there then it did with the Aluminium version. Like its lighter version, I didn't feel that at any point it was going to nick me.
