Thank you, it took me many years of experiments and studying good quality tsuba to figure out how to reproduce tekkotsu on my works,which is now one of my trademarks together with texture and patina, so I'd rather keep it for myself for the moment, probably in the future (when I'm famous enough 😂) I'll post an article about what is tekkotsu and how they appear according to my experience.
I'm only 4th Nyusen you should wonder how the First prizes look like 😄
I will go to Japan at both the study session and the ceremony, so if you guys like I'll post the awarded works here
