Comparing the Atelier, La Faulx, and Amakuni, I would say that in terms of the shave, the LF is probably the most versatile, as you can fine-tune it through the choice of baseplate. The “+” seems to be most people’s sweet spot. Using a guarded blade can make it feel closer to the classic baseplate, while a Pro Super blade can push it up to “++”.
As for the Amakuni, I really wish it were slightly less aggressive. As it stands, I am quite limited in my choice of blades, as anything unguarded requires a very good lather and absolutely no pressure to provide a comfortable shave. I seem to be alone in this opinion, though, as the Tatara team doesn’t appear to have any plans in this regard.
With the Atelier, I was only able to use a Kai guarded blade, period. It is more aggressive than I prefer, without offering any greater efficiency than the other two mentioned above.
If we are talking about maneuverability, Tatara wins hands down, followed by the Atelier and then the LF.
What disappointed me most about the Atelier was how difficult it was to remove the blade after use. Tatara, on the other hand, really did their homework with the cut-outs at the back of the baseplate.
Please take all of this as just one user’s experience. There are many very happy Atelier users out there who would see this very differently.
