Sayagaki

[Derek]

I've tried to find this answer with search function, and in google, but with no success. I read in another thread about someone having sayagaki done recently by the NBTHK. How does one have this done? Is it arranged privately, or an option at shinsa? Do other organizations perform this service? What is the going fee for sayagaki? Along the same lines, how would one arrange Honami appraisel/sayagaki/mei attribution? I have seen many nihonto with Honami appraisals, but never seen a link to their services. Sorry if this has been covered. I may send my katana to Japan for a new shirasaya, so I was curious.

Regards and Happy Holidays!
