Trivia

• The item name and description are a reference to the dataminers who discovered the secret of The Lost within 109 hours of Rebirth's release.
  • 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 Notched 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 traveling to the next floor, the music for the transition screen will be affected by it.
• In a Q&A from Twitter, Edmund McMillen considered Dataminer to be the worst item in the Binding of Isaac.
