For a while I have been switching every Other shave between safety razor and straight . but what I’ve been doing is switching every two weeks. I use everything. SE, DE, Injectors, Shavettes, straights, kamasori. So I like to keep things fresh: The first two weeks out of the month I like to keep for DE’s and the others and the rest of the month I use my Shavettes, straights and CJB Kamasori
I tend to use straights almost strictly. That’s for face and head shaving but I do still use DEs and SEs easily couple times a month.
Mon-Fri I use DEs (different one every day) Sat I use a straight, rotate through 7 Sun I use an SE, to include injectors
