Got a Real-World Weapon, Armor or Tactics Question? Mk. XXV

[Knaight]

Spears never "became two-handed", pikes came into use but they're not simply a longer spear. Spears remained one-handed, because they were almost always partnered with a shield. They were counter-weighted to keep them handy with one hand.

There were spears that saw two handed use other than pikes though - any number of hewing spears, records of normal spear techniques for two handed use (especially in Chinese and viking documents), so on and so forth.
