-The Hamon Pattern Is Done By Differential Hardening With Clay Temperd. The  Hardening Process Is Made By Utilizing A Special Clay On The Edge, So It Gets A  Different Temperature And Cools In Different Time Than The Rest Of The Blade,  Becoming Harder And Quenching The Blade When It Is Cooled On Water.
