Yes I'm pretty sure that it is stainless.
I will go to DSE tomorrow and try some proper ferric chloride.
One other idea I had was to try and darken the blade as a whole so that the weld might show a different color. Do you have any idea how to darken the color of steel. I'm thinking sorta like blueing but to a really dark grey?
Phosphoric acid will give a light grey patina to carbon steel - not sure if it'll work on stainless.
