Furthermore, in 14th-century Europe,『Touch Hole-style』guns were made.
『Touch Hole』guns were primitive guns that were miniaturized versions of artillery cannons used for taking down castle walls that worked by packing a tube with gunpowder and igniting it from a hole drilled into the tube which would fire a (stone or metal) bullet.
It was called "Touch Hole" because the gunpowder was ignited by pressing a burning metal rod through a hole.
Not long after, around the 1400s, personal handheld firearms, "Arquebuses", having the basic form of guns was likewise created in Europe. Its features were the fuse with which to ignite the gunpowder.
"Arquebus" came from the German word "Hakenbüchse" which means "pipe with hook attached".
