The Gibsons' Knife Block

Origins
This knife block was owned by the Gibsons, who first performed knife-throwing in the 1930s.

Effects
Touching the artifact causes the knife block to command its knives to come to life. The knives then pursue the user, trying to impale them unless neutralized.

Collection
Claudia Donovan found this artifact inside someone's shed. She scanned the artifact, deduced that the artifact was too dangerous for the person to own, and took it to Warehouse 13.
