Everyone loves the idea of the longsword, but did you know that poleaxes are much more effective weapons? Swords are a lot easier to carry around, which is probably why action heroes favor them.
The poleaxe is generally accepted to have been the knightly weapon of choice for dismounted combat. Many surviving examples are of high quality and decoration, which supports the idea that polaxes were used mostly by well-to-do soldiers. This is not exclusive, as The Wallace Collection's A925 is an example of an unadorned poleaxe. It is commonly acknowledged that poleaxes were favorite dueling weapons as well. There is even a slightly modified type, called a hache in French, which was used primarily for duels. This weapon had a 6-7 foot long haft and a rondel guard on each side of the grip.
Don't bring a longsword to a poleaxe fight.
