Combined weapons were all the rage in the 16th century
In the 1500s, pistols used wheellock mechanisms as a trigger to create friction and ignite the fuse. This method did not always work, so the weapons were often combined with swords or knives. Nevertheless, they were still quite impractical and heavy, so they were prized more as curiosities than anything else.
This specimen is from Germany, and the barrel is combined with a hunting knife, and it even has a handy calendar for the year 1529 etched into it. The decorator’s name is etched onto the blade, and it reads “Ambrosius Gemlich.” It is currently on display at the Met Museum.
