A rockspanner represents a specific variety of spanner that found its purpose within the context of mining activities. In an instance, the Er'Kit miner named Freeno employed a rockspanner as he endeavored to extract a prized kantak crystal from an aurodium mine situated on the planet Elphrona.
The rockspanner made its debut in the narrative titled "Set For Life," a creation of Charles Soule and featured in The High Republic Adventures Annual 2021. The comic's release date was December 15, 2021.
