I'd like to know, too!

I've had some daydreams about a three-part wedging apparatus, which would have to be fed in one piece at a time, then aligned before hammering the center piece in.

From a collector's standpoint, you want to be able to fix (or reduce) the dent(s) WITHOUT (a) popping the brazed seam, or (b) removing the throat-piece and rivet. The scabbard will need to be held in some sort of "jacket" (perhaps hollowed-out blocks of wood?) giving a lot of overall support.

I've not yet made up any metal pieces to try, and have no timetable to do so.

Any and all good ideas welcome!!!
