Cut steel decorations on Indian arms

[Kubur]

I have the little sister
And here is what i think... (who wants to be a millionaire)
All these katars had originaly 3 rivets but as you said the blade was not securely fitted. So the owners have to do some basic soldering to reinforce the thing.
Most of these katars have the same problem: disgusting and ugly soldering and it cannot be the armorer who did this lovely katar...
