A full tang katana is the sword where the tang extends to almost the whole length of the handle, which makes the blade and the handle the same piece of metal. This gives to the sword certain rigidity and makes it a very solid piece to enjoy.
Full Tang katanas are handmade swords. They can be made of various stainless-steel types according to the Carbon Concentration. The forging is the essential part of the production because it allows the samurai sword to be solid and relatively light. Commonly, the piece of metal is repeatedly heated by fire and hammered while the metal is being folded. The mounting of the different parts is a very delicate operation that has its origins deep in the Japanese civilization. Samurai are used to cherish their Katanas as their trusted partners, and they handle them with love and care.
