I'm doing some research into the weapons of Dungeons and Dragons, and one of them is a 'light' hammer that you can throw. The description says it weighs 2lbs, if that helps narrow it down. I don't think throwing is the primary intended use, but it is very much supported by the rules.
I know about Meteor Hammers, and throwing sticks like the Rungu or Iwisa, but I'm not interested in those because they are outside of medieval Europe. I couldn't find any instances of warhammers or similar being thrown on Wikipedia, or from googling and I don't know where else to look.
Was anything like this ever done in real life medieval Europe, at least commonly enough to have been recorded?
