sorry but its easier for a person whos right handed to say that kirpan should be worn from right shoulder to bottom left.....but i think its more of a ritual to say that kirpan should only be wore on the right side....cuz to be honest it wil not be practial for a left handed to wear it on their right side as the will bot be able to use it properly ( as someone said before)... and the whole aim of wearing sri ssahib is so that it could be used on such times...therfore if being practical, you will wear it on the side that you think it will be helpfull??...
and truee.....every memeber of this army has the same uniform......but its jsut like wearing a kara....its the same kakaar with same reason on why wearing it.....BUT still is worn in different sizes...why, because people have different size of wrists etc!...sme with individual, everyone could were the same unifrom but could be adjusted according to the individual....
sorry to offend anyone but my humble opinion
fatehji!
