Thread: W&B edge crumbling at macro level.

There could be some elements of the steel and/or heat treatment involved. But I think that would have to occur on a "perfect storm" basis. Old razors were manufactured with heavy emphasis on the ritual aspect of reproducibility rather than necessarily the science that is available today to guide replication of desired results. All that means is that it's possible for a bad razor blade. Rituals generally produce consistent results even if the Why questions are never answered until generations later.

The edge looks clean in your photo, meaning I don't see any lines of corrosion penetrating deep into the steel and down to the areas that are flaking away. Higher magnification may give you a better look at that though.

Without being capable of providing a better honing answer, I'm in agreement with the idea that the wire edge is getting caught in the too large honing grit of the coarser stone. A finer stone is the answer for now.
