Disappearing Knife

You could say this knife really cuts to the chase! The Disappearing Knife by Rubie Costumes is the ultimate prop for pranksters, performers, and partygoers who like their humor with a twist. With a clever retractable blade that vanishes into the handle on contact, it’s all the drama with none of the danger—perfect for stage acts, Halloween haunts, or just a little harmless mischief.

Planning a killer group costume? Pair the Disappearing Knife with a troupe of classic horror icons like Freddy, Jason, and Michael Myers for a frightfully fun ensemble. Or go the comedic route with a murder mystery dinner party theme—think Clue characters like Professor Plum and Miss Scarlet, or even a troupe of bumbling detectives and suspicious suspects. Bonus points if someone brings a candlestick!

Whether you're staging a spooky scene or just clowning around, this knife is sharp in all the right ways. Just remember: it’s all fun and games until someone pretends to get stabbed!
