A very good bladesmith mended one for me, (pattern -welded blade), and afterwards I could hardly find the join. This was done just a few years ago. 
I would like to give the man credit, but he does not want to get inundated with this type of work, so asked me to keep it quiet. 
 
I must respect that, but yes, it Is possible to have someone weld a blade and make an excellent job still. 
 
What made me think the repair above was new-ish is the way the light catches the added piece; 
It Appears to have multiple facets (or a bit wavey) on each side, not dead true as the rest of the blade seems to be. 
It Is a good join though!! 
 
Richard.
