Question about Panasonic Er-1611

I also always give answers when I have no idea and have not researched carefully, because there are enough professional answers anyway...

Hi. It simply has to do with the sharpening of the cutting blades. When they wear down, they don't become blurrier, but always stay the same sharpness. These things are shaped like a punch with a 45° angle. As they wear, the edge should still remain at a 45° angle. That's how I understand it, but I haven't researched it exactly. A super razor! Just don't hold it under water, it's only meant for dry use and I've already destroyed one that way. Otherwise, a very high-quality product.
