my apologies, the trait is called signature moves, here is the Link for it.
Its the trait I would prefer, just so the item can match its ornate appearance. If you think its too much thats fine though, could just be a fancy non-masterwork dagger, but it would be cool to have it made out of some weird material and be -special- in game.
mostly because I just realized that the material I had intended to use is actually a 3pp, called Umbrite, perhaps a bit too much.
of course I could easily take frost/fire-forged for it instead.
