I have a Higo Koshirae that was missing the Kozuka, and although I tried to find a match, I could not, so I sought the assistance of a professional - Robert Soanes - to solve my problem.
I purchased an old Kozuka that the 'motif' or design had fallen off and I asked if he could save/ restore it to suit my Koshirae. I must say that I am very pleased with the service and the result.
Not only did he make a new Shakudo Kamon to suit, he 'cleaned' the old Kozuka of the old 'glue' and made it look nearly new..! I cannot wipe the smile from my face..!
I cannot recommend his (or any of the other contemporary restoration professionals) services enough. If any of you are thinking about having something made or restored, then I can only say that you should seek (and support) their very valuable services. If I were a younger man, I would apprentice myself to any one of them...
