~ Medieval Arming Sword ~

Arming Sword (a.k.a Knightly Sword, Single-handed Sword)

What it is:

  • The classic one-handed straight, double-edged sword with a cruciform (cross) guard and pommel, used roughly from ~1000 to 1400-1500.

  • Blade ~70-80 cm (28-31 in) long in many cases, with overall sword length somewhat longer with hilt.

  • Weight typically ~1.0-1.5 kg (2-3 lbs) though can vary depending on rigidity, length, and cross section.

Design & evolution:

  • Early arming swords were made for cutting, slashing: broader blades, fuller (grooves) to reduce weight but maintain strength.

  • As armour (mail → plated) got better, the swords evolved: more taper toward the point, stiffer cross-section (diamond or flattened diamond) so the sword would thrust more effectively.

Usage:

  • One hand + shield or buckler was standard, allowing defence + offence.

  • Good balance between cut and thrust: enough slashing power, but also a sharp enough point to find gaps in armour.

Pros & Cons:

Pros Cons
Good in one-hand: allows offhand defence equipment (shield, dagger) Shorter reach than two-handed weapons like longswords or polearms
Versatile (cut & thrust) Less leverage for very strong blows compared to bigger swords
Lighter and faster to bring to bear than larger swords Against heavy plate armour might underperform if not welloiled, or when facing heavily armoured foes
