Axe is or was an anthropomorphic dog.
Axe and his nephew were the owners of a pickaxe shop during the Klondike Gold Rush, where Scrooge McDuck would usually get his supplies. They had a large variety of pickaxes, from "tried-and-true" used models to brand new versions. Axe appeared to be on rather good terms with Scrooge, although Scrooge made it clear he was looking to spend as little as possible.
Behind the scenesEdit
Axe appears in the 2007 story My First Million. Oddly, he is no longer named in the 2018 reprint of the story in Uncle Scrooge: My First Millions #1.
