Help filling tiny gap

Unlike brazing, it doesn't rely on capilary action and allows for build up without actually welding (melting) the two metals. I guess my question would be, would the brass rod melt before my brass guard?

It could be TIG brazed I suppose but it would require a careful application of heat to minimize the heat affected zone. Perhaps keeping the blade submersed in a container of water with the tang sticking out?  

I managed to get this stainless steel 'tea strainer' basket re-attached to its handles using very low amperage (5 or 6A) TIG brazing and small diameter silicon bronze wire. The basket is roughly the size of a golf ball. By comparison the larger filler rod seen below the basket would have required much more heat and would have resulted in melting the thin stainless parts instead.
