This article covers over 40 nickname ideas for the military can opener, grouped by style and usage.

Classic Military Can Opener Nicknames

• John Wayne: The most famous nickname for the P-38 can opener. Soldiers began calling it “John Wayne” because, like the actor, it was tough and always ready to open anything. The name stuck and is still widely used today.

• Use it in stories: Sharing a nickname like “The Dentist” when opening a can at a campsite can be a fun icebreaker. It adds personality to a practical moment.
