Tonight I shaved with Derby blade (razor: Merkur 23c).
Not very bad, but it is inferior to Astra SP evidently.
I mean inferiority in both smoothness and sharpness.
Especially in smoothness, Derby is far behind Astra.
For me, Derby is a two-shave blade.
Moreover, Derby causes more irritation even after first shave.
