The DSCosmetic D8 is 'inspired' by the Razorock .68 Gamechanger.
The DSCosmetic S9 is 'inspired' by the Razorock .84 Gamechanger.
And I say inspired, because the notches on the side of the base plate and the different cap shapes differ it from the RR offerings. Wasn't the RR GC a copy of the Wolfman Guerilla? At least DSC can keep their razors in stock unlike IB. I'm waiting for the titanium S9 to be available myself. I believe the T7 is based on the RR Mamba 70.
The handle is 'inspired' by Karve, but the knurling is completely different in feel.
