-The Blade Of The Sword Has Been Hand Forged And Quenched Using Diferential  Hardening, In The Same Methods As Traditional Japanese Nihonto.

-The Core Of The Blade Is Made Of Forged AISI 1045 Steel, And The Sides Are Made  Of Forged AISI 1095 Carbon Steel Folded 11 Times, Generating 2048 Layers In The  Steel, In Kobuse Lamination Style.

-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. It Is A Very  Complex Technique, As If Not Properly Executed The Blade Will Break. The Fire  Can't Be Too Warm Or Cold, Only A Good Swordsmith Knows The Exact Temperature.  The Blade Then Get Its Shape With A Beautiful Hamon Hada And Martensite (Grains)  On Its Surface.

The Perfect Combination Of A  Hard Edge With The Increased Sori (Curvature Of The Blade) With A Strong Mune,  Enables This High Quality Blade To Easily Cut Through Tatami, Straw Mats Or  Bamboo For Tameshigiri.

-This Blade Has A Full Length Tang Which Greatly Enhances The Strength Of The  Sword. The Blade Has The Shinogi-Zukuri Shape And With O-Kissaki And Real  Yokoto,It Is Well Defined With The Hamon Going All The Way Through The Boshi.
