Dan, all of your daggers i've seen have a striking 'presence', but i like this one the best. Although i collect ivory and ivory handled knives, i think the pearl suits these daggers better. And your pics have picked up some great fire in this piece of pearl. The carved end looks similar to Tulip pattern. I have a set of 6 Jos. Rodgers Tea knives with ivory handles carved into Tulip pattern, made about 100 years ago, and i'd say your carving of this pearl looks to be every bit as good.
Thanks for showing us. Beautiful (& deadly if used) knife.
