Butterfly(TTO): Feather Popular2 piece: Does a straight with 1-piece scales count?
3 piece: Gillette New Deluxe
Adjustable: Fatboy
Stainless: Feather
I own all of these.
The Fatboy gets used 3-4 times a year.
I refuse to own a Merkur again, so the closest to a 2 piece is one of my straights.
The New Deluxe gets uses maybe once every couple months.
The Feather Popular gets used for travel.
A few other razors get used throughout the year once or twice.
I use a straight about 100 days out of the year and the Feather AS-D1 gets used the other 240 day out of the year.
I'd be more than happy if I had just the Feather AS-D1, and a full hollow ground T.I. straight, or just one of those.
Butterfly(TTO) - British Gillette #66
2 piece - Gillette (#77 or #88, same razor, different case)
3 piece - Gillette NEW, either comb
Adjustable - Gillette Super Adjustable
Stainless - any razor that isn't made from steel? no idea really
Butterfly(TTO) - Gillette Slim
2 piece - Pils
3 piece - Feather stainless
Adjustable - Gillette Slim
Stainless - Pils
The only razor I now own is the Slim, having sold all others off. The Pils and Feather are really good too, and look better than the Slim. But performance wise, the Slim beats them out.
