In the light novel, Kirito also uses this pick to experimenting with "Continuous Piercing DOT Damage" while investigating with the inside-area PK Case.

Kirito uses this weapon to kill the Ragout Rabbit with minimum damage because of its rare meat.

In the web novel, Kirito throws one a Kuradeel's face to delay him from killing him when he was paralyzed, but due to the paralyze status, his aim was off and hit Kuradeel's arm instead.
