Derby about three months ago. Use them in a shavette. Never used them in a DE. Haven’t used a DE in a couple of years.
I really enjoy the 7 O’Clock Super Stainless. My father in law just brought me some of the 7 O’Clock Super Platinum (the black ones) from India and they are great too. Probably a bit smoother but I like all three kinds of the 7 O’Clocks in general. Shave on!
They are the same blade!Tiger and Tatra....9.99 on Amazon.....made in the same factory....different pakaging.IMHO, I like both the Czech Tiger Platinum and the Czech Tatra better than both Gillette SB and Astra. They perform about the same. I have tried each of them in RR Game Changer, Rockwell 6C, RR Lupo, Rex Ambassador, and Occams DE Razor. Still have to try them in one of my older Gillette's (Superspeed or Black Beauty) and a Merkur Slant. They both have performed well in those razors. I typically toss a blade after 2 or 3 shaves, so I cannot comment on how long they may go for you. All you can do is try them and decide if they work for your face, razor and shaving technique (YMMV). Over 90 percent of the reviews have been positive for these blades. The cost vs. performance is excellent.
Are you talkin’ the Swiss ones or the diamond-shaped ones made in Turkey? Or maybe the doubled-filled ones out of the Czech RepublicI just purchased 100 Toblerone: milk chocolate and almond, white chocolate and almond, milk and salted almond... I figure one or more of those will give me troubles, but they're just too darn nice on a good day I couldn't pass em up.
? what? razor blades? not?... chocolate bars? oh -SIZE][/I]>-
lol... too late. Looked like i was hacked up after that
Ouch, I can sympathise completely as my 1st razor was not mild, but medium efficiency.
I'd try the blades in the order you posted: Shark, Sharp, Astra, 7am, and Feather, roughly least to most sharp.
Feather blades can be great when used with a mild razor such as a Rockwell 6 with plate R2. YMMV.
