fate小说里UBW的全称是什么？

无限剑制的缩写
unlimited blade work

UBW=Unlimited Blade Works
名字取自Archer的固有结界：无限剑制（Unlimited Blade Works）。

unlimited blade works吧，应该是
原文如下：

I am the bone of my sword.

Steel is my body, and fire is my blood.

I have created over a thousand blades.

Unknown to death,

Nor known to life.

Have withstood pain to create many weapons.

Yet, those hands will never hold anything.

So as I pray, unlimited blade works
