Trivia

  • The item name and description are a likely reference to the dataminers who discovered the secret of The Lost, as well as the Keeper ARG's recurring usage of the number 109.
    • The item and its pickaxe icon are a play on words on the term data mining, used in the context of gaming communities as extracting data from the game files.
  • The item's sprite is a recolor of the Collectible Notched Axe iconNotched Axe.
  • If used during the Mom fight, you will be able to see a normally hidden part of the leg sprite revealing a blue skirt with yellow polka dots.
  • If Dataminer is used right before travelling to the next floor, the music for the transition screen will be affected by it.
    • Also affects the music during the Game Over screen (Isaac's last will), if activated before death.
  • In a Q&A from Twitter, Edmund McMillen considered Dataminer to be the worst item in The Binding of Isaac.
