I have now had 2 shaves with the oristo razor. And it's time to give my first small impression. First the machining quality is very good. Not better or in the same ligue as wolfman, but among the best.
I had a razorock black mamba but the love story never really started. The black mamba was for me more a "scrapping" feeling than a cutting feeling. And it was not really efficient. Before buying I asked Maurice(stashed & found) if they were some modifications made from the black mamba version and he said he did some, although they were small and were only some millimeters difference.
Although the modification are small, I notice a difference between the oristo and the black mamba.
Shaving:
I have coarse stubbles but sensitive skin.
The oristo shaves really smooth and is really, really comfortable. Maybe I think the most comfortable razor that I own. You can shave carelessly and not be afraid of any razor burn.
The shaving angle range is small. If you are not within this angle range, the razor will not shave.
The razor is efficient. Not as efficient as a wolfman standard gap, a weber, or the barbaros tr 1, but efficient.
Efficiencywise, I will put it here:
Att M1, Pils, Timeless 0.68 SB (less efficient) <- ORISTO -> (more efficient) Timeless 0.68 OC, Barbaros TR-1, Weber PH, Wolfman SB standard gap, Fatip OC
Maybe the only negative point where the razor could be better would be efficienty, but then it wouldn't be as comfortable as it is now.
I'm at this point satisfied with this razor and will probably keep it
