The “shamshir” is a curved-bladed sword intended for slashing; it was favored by the Persian cavalry in the 15th and 16th Centuries, due in part to its light weight [Stone 550]. In Society armory, it is depicted more or less as the historical artifact; a highly stylized form of it became the heraldic scimitar. As an artifact from outside period Europe, the use of the shamshir is a step from period practice.
