Are Harry's Original Razor Cartridge Refills Worth It?

Here's the bit that actually matters: it's not one blade doing the work, it's five, and that changes the physics of the shave. A single blade has to cut every hair it meets, which means it dulls fast and each pass pushes harder on your skin. Spread that across five blades and each one only has to do a fraction of the cutting, so the pressure on your skin drops and the edges stay usable longer. The flex hinge is what makes that actually work in practice, not just in theory: it lets the blade head tilt and follow your jawline instead of skating over it in one rigid plane, so you're not pressing harder to compensate for a flat cartridge on a curved face. The lubricating strip sits ahead of the blades so the glide happens before the cut, not during it, which is what keeps the drag from building. And the precision trimmer on the back edge exists because five blades in a row are useless on a sideburn line or under your nose, so it's a separate, narrower tool bolted onto the same cartridge. The one catch worth knowing upfront: this only clicks onto a Harry's Original handle, so it's a refill, not a standalone razor.
