Personally I would be ready to trash it 🙁
Based on my experience this looks to require the removal of a minimum 15mm.
It's never going to be the same, and I really do not have any faith that anywhere you take it could do anything other than destroy it further.
You might be looking at mailing it to a specialty shop.
I would take a breath and move on with life.
I'd also like to share my experience as a home cook that makes everything from scratch, and I have learned that expensive knives are a huge money sink, they always crack or chip, they always end in tears.
I'm rock solidly convinced that a $10-20 German steel chef knife, abused with a sharpening wheel and a hone and replaced frequently is much better in the long run.
