Stage 1 - Hilt has been separated from blade, break in hilt repaired with steel pin and a heavy-duty cyamoacrylic gel used to glue scales onto knife blades:
I've also worked on the socket for the blade's tang (barely 1 1/2 inches long) so that it rests more properly into the hilt.
Next is to finish cleaning the blade a thoroughly as possible without removing too much material or otherwise stressing the metal. Then it's on to the ferric chloride etch to bring up the pattern. More pix as the job progresses!
