Medieval Swords: Slashing Versus Thrusting

Burnished and shiny like a mirror, the sword, usually about three pounds, was a double-edged instrument of death. For most of the medieval period, at least north of the Alps, its main use was for slashing and hacking, a method that may have given the best results against chain armor. In the Mediterranean, probably due to Roman influence, the thrust was more common. It required less physical strength and stamina and could be more deadly, for a single hit on a major organ would kill.

The design of the sword did not change much in the period 800-1350 [C.E.]. The emphasis was on sharp edges more than a sharp point. But by the fourteenth century, as mounted soldiers switched from chain to plate armor, the old system of slashing was revealed to be insufficient. The tendency was to emphasize the point, which would exploit the joints in plate armor. Its length depended on the holder’s stature, but normally it was about 100 centimeters. According to L. Tarassuk and C. Blair, the typical sword of a fourteenth-century knight was long, with the blade itself being almost 1 meter.
