Why did the springs become brittle?

Difference between a spring and other ferric material is that the spring has been hardened and then the temper has been drawn.

A weapon is heat-treated in the same way, that is, it has been heat treated and often the temper that it has been drawn to is the same as a spring.

A keris is also heat treated, but with a keris, because of the laminate construction probably only the hardened edges of the core will react in the same way as a spring, ie, they must become brittle.

After reading this I would hesitate to use electric rust removal on any keris except perhaps the old junky corroded ones that have lost any hardened material long ago. I would not use this treatment on any keris that I valued.
