About a year and a half ago I made the switch from the disposable triple-blade cartridges to a full classic setup: Edwyn Jagger safety razor, Astra blades (made by Gillette in their St Petersburg factory), upper-end shaving brush and Proraso soap.
Having very sensitive skin, from being able to shave every third or fourth day, I can now do it every second day. It takes longer and I do cut myself, but without the chronic irritation I used to suffer from, so by the time I apply the aftershave (Nivea works fine for me), the cuts are already closed and I feel like a million bucks.
Next up, Merkur blades from Germany, then once I’ve mastered those, maybe I’ll go for the holy grail: Feather blades from Japan, or as one Amazon user described them, the Hattori Hanzo of shaving blades.
