Now Eric, 
 
In the cases you just quote above, Do you think these were repairs, rather than a technique used in manufacture? 
 
To me it Sounds like a repair. 
 
I do have one broad-bladed tulwar that was repaired at some time in its working life.  Very well done as well.  The break is just forward of the centre of the blade. 
I will see if I can find a picture.
