The Parthenon razor looks very interesting. It should be noted, though, that it's design is closer to that of the Futur but TTO. (Does that make it more like a Merkur Vision 2000?)
The part I found interesting was the following comments from QShave:
"The two razors are different in many ways. One of the major different is adjustable mechanisms. Rockwell's T model's mechanism is the same as Gillette Fatboy produced in 50s which uses only 4 bars to adjust the blades; Parthenon's entire blade tray moves when adjusting, the mechanism is similar with Merkur. The reason we did not use the 4-bar mechanism is that we found the bars were easily interfered with the butterfly open tops, and it affected the shaving experience and had relatively higher defect rate. We chose our technical & design solutions which fits our design goal (better shaving) and manufacture capability. Don't get me wrong. I think Rockwell's T model could be a good razor if they had solved the problems which I mentioned before. And actually our factories had received several inquiries of making the 4-bar adjustable mechanism razor. We had spent quite some time to study it, and the realize the manufacture difficulties. I think that's why Gillette had changed the design 4 times between 1958 and 1961, and eventually stopped producing it. I checked the Rockwell's project page, and their project is already delayed for over a year due to the manufacture issues."
As I said previously, at the time, Gillette had over 50 years experience in making DE razors and 20 years experience in making TTO razors as well as specialized tooling. Rockwell, on the other hand, is a modern company which outsources its design and manufacturing. As a result, I think they are encountering the issues that occur when design meets reality.
