Here is a nifty vintage swirly pastic handled butter knife by Stanley Stainless.  I have a weakness for old swirly/marbled plastic...  This one sort of, kind of, suggests a wood look- with a deep reddish brown handle with lighter red/orange swirls.  IT IS USED and has some scratching to the blade.  No chips or cracks to the plastic.  Maybe you like swirly plastic too?  Or maybe you need to complete a set. 
If you need additional photos or have any questions, please let me know.  I'll be happy to try to help.
