Kfalcon:
There was a Star Wars prop book released by DK publishing in 1998. The authors were given creative license to "make up" some of the bits we never "completely" saw on film. The stir stick/paddle was in the costume's pocket, not the knife. Same goes for the detailed "sonic beam weapon"...not connected to any film. DK invented a lot of stuff, such as an interior to a storm trooper helmet that also had no lineage to the films. I have no idea if ILM made the new additions to the old props. I personally hate what they did in the book. It appears it was only done for the book, but, to me It's like repainting King Tuts tomb in warm earth tones. Don't mess with history. Added foot note: At least one of the Star Wars prop exhibits I went to had Icons replica sabres on display along side real props with no disclaimer. If you want to be movie accurate, just use the print squeegee and stir stick. There are instructions here on TDH
