I concluded that all three types of these blades is the best for heavy beard and sensitive skin(for me at least). who is more sharper between the three ? who is more smoother between the three ? who is more longevity between the three ? what's your choice? Perma-Sharp Super Gillette Silver Blue Gillette 7 0'Clock Super Stainless (Green)
I have used a lot of these three blades. The 7 O'clock Russian Green is a step below the other two but not a bad blade. Both the Perma-Sharp and the GSB are nice sharp blades that give me 5 comfortable shaves. I have a couple hundred of each and really enjoy them both. The GSB is less expensive and slightly smoother than the Perma-Sharp Super in my opinion. If the price per blade were equivalent, it would be a push. It is not so I rank them GSB, then Perma-Sharp Super, then Gillette 7 O'clock super stainless.
I like both the Perma Sharp and the GSB. I think they are very similar. I give GSB the edge based on price and smoothness. (The smoothness my just be more familiarity too.) The 7:00 greens never were a favorite. I cannot really comment to longevity because I am a three and out guy.
Only have used the GSB's and the Greens. In my Focus shaves, the GSB's always bested the Greens. But I wouldn't want to live on the difference. I'm a six day a week(Sun-Fri) shaver. Both lasted all week, two and a half pass shaves.
Permasharp, then greens followed by the gsb. Pricing is a little different in Aus and the permasharp are the cheapest, and fortunately best performing for me. Sent from my iPad using Tapatalk
I only have used the GSBs and the Greens. The GSBs were some time ago (and I don't take notes really) but I liked them better than the Greens. The GSBs were smoother for me.
I haven't used the Perma-Sharp, but of the other two, I wouldn't even put them in the same category. The SilverBlue are among my top choices in blades, and the 7 O'clock green are right beside Derby in dead last... Just shows how individual opinions vary!
For me, it's really tight between the GSB's and the Green's. I wouldn't want to live on the difference. Throw Voskhod into the mix and it gets even tighter.
I voted for Perma-Sharp Super. It's not that sharp but it was a fairly good blade. It seemed to be Gillette's take on Voskhod. I gave GSBs multiple chances but they just never worked out for me. The Russian green 7 O'Clocks didn't feel like anything special from what I remember. I can't comment on longevity and differences in sharpness are often so arbitrary that it's tough to judge, but Perma-Sharps are unquestionably the smoothest of the three.
A lot of people seem to prefer the GSB over the Green, but my experience was the opposite. I constantly got nicks and rough shaves out of the GSBs, but the Greens have always been great. I've not used the Perma-Sharps, so can't weigh in on those.
GSBs are largely considered to be done of the sharpest blades available (just behind feather). What I would like to know us how these all compare to Gillette 7 o clock sharp edge yellow blades
Few blades can hold a candle to the yellow SharpEdge blades. I put them in my top category of blades, which otherwise only includes Kai, Feather, and maybe Nacet. The SharpEdge felt almost as sharp as a Feather the very first time that I used one, and it also had the advantage of being quite smooth like a Voskhod. If price is a factor, then they are simply the best blades around. My only critique is that I don't like the wax dots. Otherwise they blow GSBs out of the water but that doesn't mean much coming from me since I had terrible luck with GSBs.
For me, the greens are my chosen blade and I find them a hair above the Perma-sharps. They are quite close but I find the greens to be a tiny bit smoother. I can get about 10 shaves out of a blade if I push things but I usually stop at 6 since much after that I really have to go over a spot multiple times to get a closer shave. I never really liked the GSBs in any of my razors and found them to be sharp but quite rough.
I have never used a Perma Sharp but I have used the GSB and Gillette 7 O'Clock Yellow. I place Gillette 7 O'Clock Yellow easily above GSB. Gillette 7 O'Clock Yellow are great blades despite being overpriced !!!
