The gladius isn't technically medieval , but at least Taw has switched from discussing firearms to long and pointy metallic objects. That's progress!
FF - *Shakes head* And from a Mod too...
I'm surprised that no-one has mentioned the rapier. Fencing was a great way to dispose of your enemies (assuming that you are faster than they are)

. Fencing is still around these days, but fencing clubs are rare here in Aus. There are only two in Victoria (that I know of).
Now here is the best weapon ever conceived; the horse! Think about how different history would have been if the horse had never been trained, bred and introduced into warfare! No
Chevalier , no Dragoons, etc. In my view, they truly revolutionalised the development of medieval warfare.
