Hello Milandro,

As mentioned above (post #21), I'm not favouring etching with ferric chloride. The stain will often exhibit pretty warm colors (i.e. rusty), sometimes after some time only.

Even if one has experience in its use on modern pattern-welded blades, there is a chance that leftover chloride ions will keep nagging on a blade, especially with antique blades that are more likely to have crevices from cold shuts, eroded surfaces, etc.

Pretty much all Moro aficionados are nowadays utilizing warm diluted acetic acid. While the resulting pattern will be more subdued, it certainly seems close enough to what real user blades probably looked like.

Regards,
Kai
(BTW, I see that I failed to answer David's post - will do ASAP)
