• This is best answered by one of Braun's engineers. But as an owner of this trimmer, I guess I'll have to do. I have never noticed anything of that nature. If you think about the difference between sharpening (removes metal) and honing (straightens the edge at a micro level), it may be that "self sharpening" is really "self honing" which would make more sense to me. Regardless, I've certainly never seen anything that hinted of a metal shaving.

• No, Self-sharpening blades are typically found in rotary paper cutters. The base of the paper cutter, on the cutting edge, has a strip of metal along the entire length of the cutter. As the cutting blade is used to cut paper, it also rubs against this metal strip, causing the blade to sharpen
