Stulorne Blades

"To the eye the sword appeared blunt, but when I touched it..." "You're lucky. I've seen those blades in action. They're forged using magic."

- Merlin and Gwaine

Stulorne Blades are swords that have been forged using magic. They appear blunt to the eye, but in reality are razor sharp.

History
Dagr and Ebor used Stulorne Blades when they attempted to kill Arthur during Camelot's annual Mêlée. They obtained the blades from the sorcerer Cylferth, whom they killed afterwards.

Merlin accidentally cut himself on one of the blades while cleaning their room, which eventually led him, Gaius, and Gwaine to discover Dagr and Ebor's true identities.

During the Mêlée, Gwaine disarmed Ebor and used his blade to kill him and Dagr (Gwaine).
