In the forest of Brethil, Curufin, wearing the knife sheathless by his side, and Celegorm attacked Beren Erchamion and Lúthien Tinúviel in an attempted to kidnap the latter. The brothers lost the fight and the knife, along with other spoils, was taken from Curufin. During the Quest for the Silmaril, Beren used it to cut through the Iron Crown of Morgoth and free a Silmaril. However, its blade snapped as he tried to cut a second jewel and Morgoth stirred as a shard grazed his cheek. Beren left Angrist behind as he escaped.
 Other Versions of the Legendarium
In Quenta Noldorinwa the knife of Curufin remained unnamed and it was referred to as "the knife of the treacherous Dwarves". Also, there it is stated that its maker was a dwarf from Belegost, not one of Nogrod.
