"The Astra Superior Platinum 'Green Pack' is the ultimate five-star shaving blade because it perfectly balances high-end sharpness with an incredibly smooth, platinum-coated glide that gives you a professional, irritation-free shave every single time for a fraction of the cost."
The 7 O'Clock Black (Super Platinum) is a total beast for a thick beard. While the Yellows are like thin, fast lasers that slice through hair, the Blacks feel more substantial and way smoother. They’ve got this platinum coating that makes them glide, so you get all that sharpness without the skin irritation.
Compared to the Yellows, the Blacks are definitely the "premium" version—they stay sharp way longer and don't get that "toothy" feel after a couple of shaves. They’re almost like a Kai, but the Kai is still the king if you want pure, raw aggression. The Black is more of a refined power hitter that gets the job done without the bite.
If you’ve got a thick beard and you’re sick of blades tugging, the 7 O'Clock Yellow is a game-changer. These things are "lasers"—thin, ultra-sharp, and built to slice through coarse hair on the first pass. No dragging, no resistance, just a clean, crisp cut. It’s a high-performance blade that actually does the job. They’re almost like a Kai, but the Kai would be more aggressive.
This is a top-tier blade that strikes the perfect balance between sharpness and comfort. For a thick beard, it’s a massive upgrade—it’s efficient enough to cut through coarse hair without the tugging you get from milder blades.
Compared to the Nacet, it’s a smoother, more "cushioned" ride, though the Nacet has a bit more raw biting power. Compared to the Kai, it’s more forgiving; while the Kai is wider and more aggressive, the Silver Blue is the perfect daily driver that gives a close shave without the irritation. If you need a blade that actually performs but doesn't butcher your face, this is it.
"I cannot speak highly enough of the service provided by this seller. He is professional, helpful, and the other blades he has recommended to me have been outstanding. It is clear he knows his products and cares about his customers.
Regarding the Personna Platinum (Red) blades: while they didn't quite work for my specific needs, I believe they have their place. I have a very thick, coarse beard, and for my hair type, these blades felt a bit too mild and tended to tug. However, for someone with a lighter beard or very sensitive skin, these would likely be a very comfortable, smooth option.
I’ll definitely be returning to this seller for more of the sharper blades that suit my growth, as his service is second to none. If you have a heavy beard, just ask him for his more aggressive options—he has plenty of great ones."
