What are the usual dimensions of a Lohar?......because this certainly looks like one....this is a part of a photo posted by DhaDha after a visit to Jodhpur, India. If the Lohar is a smaller version....perhaps it evolved into a secondary weapon....possibly used as a main gauche you could parry or hook your opponent's sword.
