(This sword is an acient eygptian sword, I went on a web site and found this)
The khopesh was primarily a slashing weapon, and the curvature of the blade meant that, upon impact, a greater pressure was exerted on the target that would be delivered by a straight edge. Because it was cast rather than forged with a hammer, the blade was also thicker and heavier than a straight equivalent would have been. Normal procedure would have been for a soldier to defend himself with his shield, while using the khopesh either in wide cuts at the enemy's body, or to strike at the head as he would use a mace.
Because copper and bronze are relatively soft metals, the thick edge of a khopesh could be blunted easily, and it is therefore unlikely that a khopesh would have been used to block or parry blade-to-blade. However, the design does include features clearly intended to make the weapon more versatile in combat.
The tip is weighted and in line with the hilt and base of the blade, so it was perfectly possible to thrust or jab at an opponent's face. The non-sharpened inside of the curve, if the weapon was reversed or dual-wielded, could be used to catch an opponent's arm or weapon and deflect it. Prior to the New Kingdom's straighter-bladed variant, the weighted tip also had a rear-facing spur, which could hook the edge of an enemy's shield and pull it away, thus exposing him to attack.
