I am so sorry, I don't know what to say.

What would it cost to mail it to the US for a trusted professional honemiester to look at/work on?

Not knowing the mailing issue, I'd hope you can find a member here in Europe to whom you could send your other razors when they need honing. Please do not take any others to that place. Maybe start...

I would venture to say that you should have a conversation with them about what techniques (and stones) they used to hone your Boker.
