Today I've compared an AC straight and an AC safety razor.
Started with the DX. The second was Hawk v.3 (not pictured).
Well, after half a pass I switched back to the DX: the SE razor did too much dragging and just didn't cut.
Perhaps due to an old blade: Feather AC Professional (6 and out).
Or maybe the lather was not perfect (Mike's soaps are not famous as fuss-free).
Anyway. The last pass with an AC-SR was a breeze. And I really like Zingari balms.
