Or in other words, razors that hold blade most rigidly. Lets see if we can make a list for reference.
I have tried two of these razors and for me they always gave irritation free and smoothest shave. I would personally only use such razors since they get the job done most comfortably.
Merkur 45
RR Baby smooth(?)
RR Stealth Slant(?)
Ikon 102 slant(?)
Wolfman razors
Mongoose(SE)
Feather AS D2
There has to be some more.
