Another method might to be a switch I've used for years. It's a GREAT set up for the smash knife climax!
B/W knife is in the right hand ready for the paddle move.
Left hand goes into pocket and pulle the W/W knife and places it between the index finger and middle finger of the right hand.
Do the paddle move with the B/W knife only, showing it to be black on both sides as in the regular routine.
Tell the spectator that you keep one knife (left hand removed the B/W knife and openly pockets it in the left side pocket and grabs a handful of the little knives) in your pocket and the other in plain sight.
Left hand comes out in a loose fist. Do a cigarette push-in vanish into the left hand (right hand retails the knife, but the spectator thinks you have done a switch to the black knife).
Turn slightly to your right and, as you dump the little knives into the spectator's hand, pocket the white knife in the right pocket.
I showed this to the late Heba Haba Al when we worked at the New York Lounge and he told me that this was very similar to an Ascanio sequence with the smash climax.
Turst me, this kills and leaves you clean.
