Arsenic salts on indonesian blades

[stekemest]

Hello everyone,

I have recently acquired three indonesian weapons, one keris and two spears. I know that kerises have usually been etched with arsenic (warangan). Now I would like to know if the arsenic salts on the surface of the blade still poses a threat to human health, and if this warangan was also used on spearheads.

Thank you for any answers.
Peter
