Here is what we have to work with, the broken handle and a boken handle from a parts knife that should match close in color and jig pattern once worked down.

It needs a bit of fitting

getting closer

now I flatten the side of both handles so they butt up flush with little or no gap.
I notch the piece so it will fit around the pins and glue it on

a little filing, sanding and polishing and viola a nearly invisible patch. nowq she's ready for the pocket.
