If I had to pick just one it would be my Gillette Slim adjustable. But I have a few that I switch between so each couple weeks I have a different daily razor.
I rotate (in no particular fashion) EJ de89 , Muhle r41 , merkur 37c slant and a Utopia. I just finished using the utopia for a week trying different blades to see what works best, I'ts my travel razor . Sometimes I use a straight. The r41 is new so I'm just getting used to it. Ramble Ramble Ramble, So to answer your question, I don't have a daily shaver. Welcome to the Den!
Current favorite is a Dovo Bismark 6/8. Previous to that and still an awesome razor a Wacker Jungmeister Favorite DE is a toss up between an ATT M2 and a 58 fatboy.
I do this little 30 Day thing.... This month is Derby Extra and Fatip Grande, with Arko and Veg...all month.
That would be my Merkur 180. I keep going back to my it. It has become the standard that I use to compare all the others.
Boy that's a hard one, I switch around from the vintage to the moderns but I really like the Merkur 180 and the ej89, vintage the techs or my Bostonian
futur and FB.....have a few others but mainly those....enjoy my injectors from time to time as well as the slims and BB.
I never use the same razor twice I'll use a Fatboy, slim,super adjustable short, long in nickel, then a gold then a blue tip then my birth year super speed and then I start all over I also never use the same soap twice in a row or aftershave twice in a row never even use the same brush twice in a row.
VARIETY, i use a different one usualy daily. Every now and then I'll visit the same one two days in a row.
When it comes to shaving I'm a serial monogamist. I've had former razors but am presently with the Merkur Futur... at least until something sexier comes along. Blades, however, seem to be nothing but one night stands.
