Review (5/5): Great prop for theatre and musicals!  Stage Manager approved!
Great prop for a musical we produced. Always buy extras as this technically is a novelty toy, and they get lost easy
They functions perfectly and really looks like a real switchblade onstage.
If you like, you could paint the black comb with metallic silver paint. Just use a thin coat, don't get any paint in the hinge and let it dry completely before closing.
There is also the slide lock which does function and locks the blade. We have never had issues, but you tape tape it open to prevent and issues trying to flip it open fast.
I answer comments if you have any questions!
