Kai, I have tried cold blue on a normal contrasting pamor blade but it does not produce acceptable results.
However, on pamor sanak, which is all ferric material, it can produce more or less OK results, and for touch-ups of worn areas on a blade that has contrasting pamor it works really well. I'm talking about very small areas when I mention "touch-ups", areas less than, say, 3mm X 3mm.
What you say about sensitising the blade prior to warangan by rubbing a cut lime over it is better achieved by brushing with strained juice from Tahitian lime, freshly squeezed.
