Wow! Great lot of knives, Lew. Congrats.
The small dha is really sweet. Mark has a few like this, and I believe he had Philip Tom polish one (two?). These come in a wide range of quality.
I'm with Teodor on the tusk-hilted knife. The scabbard and ferrule treatment really do look like a dha. The blade profile is a bit unusual for a dha, but not terribly. When you get it, if you could post some close-ups of the scabbard base and silver treatment, identification might be easier.
The tusk makes this something I now covet.
