Caliburn: Golden Sword of the Victorious (勝利すべき黄金の剣, also translated as Golden Sword of Assured Victory?) is the holy sword that is the symbol of the king pulled from the stone of appointment by King Arthur under the guidance of Merlin. With the words "Whoso pulleth out this sword of this stone is rightwise king of all England" engraved in a golden inscription on its hilt, it became the symbol of England's king of knights once it was pulled from the stone. It looks similar to Excalibur, which she later received from the Lady of the Lake, but it is a different sword and its characteristics as a Noble Phantasm also differ. It is not as strong of a sword as Excalibur, as the swords of kings are often lowered to the role of fancy decorations due to being symbols of authority. The cost of being a dazzling sword is that its grade as a weapon is inferior to Excalibur. It was broken in a battle in which the rules of chivalry had been broken by Arthur, and she later received the new holy sword of the Lady of the Lake. Despite that, she has a stronger attachment to Caliburn.
Merlin claimed that she would "no longer be human" after taking hold of it, as a king is someone who kills everyone to protect everyone. Once she pulled it from the stone, the area filled with light, making her something inhuman and stopped her physical aging. Many knights thought it to be ominous while most praised their master's immortality as divine. After the sword was destroyed, Avalon later granted the same properties. Though it is a weapon forever lost that will never exist again, Shirou Emiya, upon seeing Saber's memories in his dreams, becomes able to project it during the Fate route. Due to having no real experience with projection, the weapon mostly uses the stored memories of Saber wielding it to attack and defend while merely pulling Shirou along. Despite being weaker than Excalibur, it is still a very strong sword capable of cutting through God Hand. Once used by Saber and Shirou at the same time, they are able to smash through Berserker's axe-sword, slash into his body, and release an attack of light similar to Excalibur from the inside that kills him seven times with a single attack. It is derived from swords with similar legends, Gram and Merodach, and if it is to face them, it would lose due to being a newer incarnation.

Golden Sword of Assured Victory
A holy sword appearing in Arthurian legend, just like Excalibur. Refers to the sword Arthur pulled from the stone when he became king. For Saber it is a friendlier, more nostalgic sword than Excalibur.
As symbol of the king’s authority, it is more extravagantly adorned than Excalibur. Because of this, its performance as a weapon is also lower than Excalibur’s.
In the legends, Caliburn is broken when King Arthur engages in a fight contrary to the principles of chivalry. Afterward, he receives a new sword, Excalibur, from the fairy of the lake. There is some debate about whether or not Excalibur was reforged from Caliburn, or if they were two completely different swords from the start.
伝説の中でこの剣は、アーサー王が騎士道に反する戦いをしたことによって折れている。カリバーンが断れた後 、湖の妖精によって新たに与えられたのがエクスカリバーだ。また、伝説におけるカリバーンとエクスカリバー の関係については、同じ剣が作り直されたという説や、まったく別ものであるという説など諸説が 存在する。
