I held the ends of a paper clip together as the guy soldered the meeting parts with just a cigarette lighter. Never burned my fingers. Just a thought...
Isn't silver soldering high temp soldering? It is a form of brazing as far as I know. Also a lighter flame I think is in the 600-800 C which will blow the temper of the blade too.
I personally would try and hone out the crack to see if it works.
