Jedi Forge
From Wookieepedia, the Star Wars wiki.
The Jedi Forge was an initiation ceremony carried out by the Jedi of Tython. It involved the Jedi channeling Force power into metal swords, for example Jedi katana, in order to make them extraordinarily strong.
[edit] Behind the scenes
Although the Jedi Forge was first revealed in The New Essential Chronology, author Dan Wallace stated that the concept was already developed for a future source yet to be revealed. [1]
