Make you a deal, next time you are spending a lazy Saturday in sydney let me know and i will prepare some 15n20 and 1075 and we can make some Damascus.
If you finish it quick enough we can even crack out the 2x72 rough shape it and heat treat in the oven. You probably won't have time to finish gringing and temper though

Pretty sure it would have contained cyanide rather than arsenic.

I can remember 52 years ago first year at high school surface hardening projects with (Hardite) and being told it was full of cyanide, and brazing with borax as a flux.
