In Celtic mythology, Gáe Bulg ("notched spear") was the spear of Cuchulainn, given to him by Aife. Gáe Bulg was notched to ensure it would do great damage when taken out of a body; it was made from the bone of a sea-monster that had died while fighting another sea monster.
Cuchulainn killed his son, Connla, and his close friend Ferdiad, with the spear. He perished after losing the spear, tossing it at a satirist.
The Gáe Bulg (also Gáe Bulga, Gáe Bolg, Gáe Bolga, meaning "notched spear", "belly spear", "bellows-dart," or possibly "lightning spear") was the spear of Cúchulainn in the Ulster Cycle of Irish mythology.
The Gáe Bulg had to be made ready for use on a stream and cast from the fork of the toes.
Gae Bolg is the weapon of Astaroth Aslan in Trinity Blood.
