Isekai Kenkokuki - Vol. 8 Ch. 56.1

[AnotherDuck]

Pikes and the superior halberd come later historically.

In a large portion of fantasy, any weapons used before guns become the main weapons are tossed in with little regard for historical accuracy. You see spathas, long swords, arming swords, rapiers, smallswords, falchions, sabres, katanas, spears, poleaxes, halberds, and everything in between. All at once.
