A simple Xiphos, shortsword known as the hoplit secondary weapon, used for short range in the battlefield. It was also the ancestor of the roman gladius.
The strap here is already designed and scaled to match correctly with a standart human body, from the pelvis (left side) to the top on the right shoulder. You just have to rotate it by 180° and adjust the attachment ring a little bit.
The blade itself is scaled to fits perfectly in the scabbard.
