The "Stones in a Cobblestone Sidewalk" analogy always works
by: Anonymous

Oh my goodness, is that video real?

Anyway, it's like working with plaster when we were kids... Why is it, that no matter if its gypsum plaster of paris, or reinfored gypsum plaster, or Portland cement, or concrete... why is it that these materials always SHATTER as oppose to bend/deform? It's not because these materials are weak (e.g. the concrete): it's because the RATIO BETWEEN THE HARDNESS OF THE PARTICLES AND THE STRENGTH WHICH GLUES THEM TOGETHER is too great; that is the particles are too hard/shattery for the glue between them to hold them together.

Hard rubber is tougher than cheese, but both do not shatter. Glass is tougher than egg shells, but both shatter... With a sword, you want something that is like rubber: IRON is an excellent candidate. As it becomes steel to hold a harder edge, it becomes more ~shattery~, but not too much in many cases...

If you put enough chromium in the molten iron when the steel is made in the foundry, the chromium will automatically form chromium carbides in the mixture--particles that are much, much harder than steel--and the more you add, the more of these carbides form. In order to make a steel truly stainless, you need quite a bit...enough to turn your sword into being like a cobblestone sidewalk--easily broken between the stones--instead of the ~glue~ that's between the stones, which is by comparison much tougher
