Actually, time for research. Fragarach is a sword from Irish Mythology. It's also known as 'the Answerer.' It was forged by the gods, and wielded by several Irish heroes. It's powers are that none can move or lie with the blade at their throat, and that the user can control the wind. It can also cut through any shield or wall, and dealt wounds that would never heal.

Umm..... inconsistent much?
