If it's a Lloyd Hale custom, and the mark looks like his, he often gave his blades a mirror polish. I don't see any with a plated blade. Nor can I think of any reason why a guy who gives many of his blades a mirror polish would go with plating.
I can't think of any good reason to have a plated blade. I'd rather deal with rust.
If it's mirror polished, and if you can't contact the maker, your only choices are to sand/polish the blade yourself, find someone else to do it, or live with it the way it is.
If it's plated, the knife would have to be completely disassembled to get the blade re-plated.
