Were the chakram's only used by the Sikhs?

Hi, just a humble request that the posts remain respectful of each others opinions and beliefs, best way would be to keep religious views to ourselves,

My two pence, would be that its a possible reference(although not favourable ) to sikhs due to the "iron dishes" as Nihung Singhs (sikh warriors) only eat out of iron, and are regarded as Sant-Sipahi, or Saint Soldier
