Hello Alan,
thank you for your explanation about pamor steel. My sources are obviously wrong and it is not just one. Someone made a translation mistake or so and many German authors adopt that mistake.
Ferric chloride on antique blades is difficult! Some users have very good results, my results with low concentrated FeC-etchants are always bad. FeC causes pitting on my blades and create a nasty surface. A good alternative is Iron III Sulfate with a concentration between 10 and 20%. Iron III Sulfate is a very weak etchant and it is almost impossible to ruin a blade with that etchant.
