I’ve never used a Razorock old type, but I’ve been eyeing the head due to its low price and good reviews. Seems like a good introduction to open combs
I love my OC razors. I usually use a NEW long comb, but I also have an old Wade and Butcher DE which is essentially an old type clone from the 20s. Excellent shavers. Give them a shot.
The RR Old Type shaves nothing like the vintage Gillette version, in spite of the name. If I were shaving every day I'd use it a lot more. I'm shaving two or three times a week so my New Deluxe, RR GC OC, Schone OC and vintage Old Type get the most use.
