Also known as: UBW Chant · UBW Copypasta · Unlimited ___ Works
Unlimited Blade Works is a copypasta and meme based on the incantation used to activate the noble phantasm of the same name from the 2004 visual novel Fate/stay night1. The chant, beginning with the iconic line "I am the bone of my sword," spread across forums and imageboards starting in 2006, spawning countless parody versions and one legendary exam essay that earned its author a D+5. It's one of the longest-running anime copypastas, with the "Make Your Own UBW" format thriving across communities for nearly two decades.
Overview
Unlimited Blade Works, both a fictional ability from the Fate franchise and one of anime fandom's most recognizable copypastas. In the source material, it's a Reality Marble, a pocket dimension filled with countless replicated swords, belonging to the characters Archer (EMIYA) and Shirou Emiya1. Activating it requires reciting a specific incantation, a dramatic chant that reads like dark poetry about a life forged through endless combat and weapon creation3.
The chant's dramatic structure, with its rhythmic lines building to the shouted title drop "UNLIMITED BLADE WORKS!", made it irresistible for parody. Each line follows a predictable pattern that's easy to riff on: identity declaration, body metaphor, accomplishment claim, duality statement, suffering acknowledgment, tragic irony, and a climactic invocation4. This rigid template is what makes UBW such effective copypasta material.
