A weapon built around a small amount of iron
A spear concentrated its costly metal in a relatively small iron head. Its long shaft could be made from wood, so making another weapon—or replacing a damaged one—did not require a smith to forge a whole blade. If a shaft split, the iron head might still be usable; if a sword’s blade failed, repairing or replacing it demanded far more skilled metalwork.
That difference mattered when equipping a crew. A sword blade had to be forged, shaped, and hardened as a single working weapon, a demanding process in a period when good iron was valuable. Spears were not effortless to make, but their simpler construction made them a more practical way to put weapons in many hands.
Reach made the bargain useful in a fight
The spear was not merely a cheaper substitute. Its length let a fighter thrust from farther away than a sword could reach, and the same basic design could be used to stab or, in some cases, thrown. In a close formation, several spear points could threaten an opponent before that opponent got close enough to strike with a shorter weapon.
Swords still had a place: they were portable, useful at close quarters, and valuable signs of wealth and standing. But a crew did not need every fighter to own one. The spear joined reach and battlefield usefulness to a lower material cost, while a sword could remain a prized possession. If a fight or an accident damaged the wooden shaft, a replacement could restore the weapon without starting again with a sword blade.
