Though single-edged cutting swords already existed in the Ancient world, such as the ancient Egyptian and Sumerian sickle swords, these (usually forward instead of backward curving) weapons were chopping weapons for foot soldiers. This type of weapon developed into such heavy chopping weapons as the Greek Machaira and Anatolian Drepanon, and it still survives as the heavy Kukri chopping knife of the Gurkhas. However, in ancient China foot soldiers and cavalry often used a straight, single edged sword, and in the sixth century CE a longer, slightly curved cavalry variety of this weapon appeared in southern Siberia. This "proto-sabre" (the Turko-Mongol sabre) had developed into the true cavalry sabre by the eight century CE, and by the ninth century, it had become the usual side arm on the Eurasian steppes. The sabre arrived in Europe with the Magyars and the Turkic expansion.[5][6][7] These oldest sabres had a slight curve, short, down-turned quillons, the grip facing the opposite direction to the blade and a sharp point with the top third of the reverse edge sharpened.[8][9]
