4pcs Retractable Fake Knife Slim Toy Weapon Plastic Prop Dagger Trick Blade for Halloween Fools Day Party Cosplay Joke Gadget Prank Gag Black

If you need a tiny prop that will instantly turn your living room into a low-budget action movie (starring two teenagers, one very confused dog, and an unfortunate watermelon), congratulations — the Sujosa 4pcs Retractable Fake Knife is your new best friend. My boys discovered these and immediately appointed themselves espionage twins. Within five minutes they’d choreographed a slow-motion duel that looked suspiciously like interpretive dance. The dog, bless him, watched from the couch like he was judging their life choices and hoping for snacks. Then we moved on to the watermelon test (because of course we did): dramatic approach, heroic “stab,” and — surprise — the blade retracts exactly like it should. The watermelon lived to roll another day, albeit with a mild identity crisis. Pros: Ridiculously convincing for photos and dad-grade theatrics. Kids loved the click-and-retract action — very satisfying, zero damage. Dog approved (mostly), though he now sighs differently when the boys “train.” Cons: May inspire elaborate spy plots at 10 p.m. that you will be roped into directing. Teenagers gain a sudden and alarming confidence in their dramatic monologues. Final verdict: Great prop, harmless fun, and 10/10 for family entertainment value. Just maybe test it on fruit first — the watermelon appreciated the rehearsal — and keep it away from anything truly sharp.

I love this fake knife. I don't think I needed 4 but why not. I was able to fool my 15 yo son and husband but I think the gig is up. I may revisit the knifes in a few years but I don't know that I can get away with it again. It's sort of like rewatching the Sixth Sense and being surprised..just can't happen.

These look amazing! Not the highest quality, but I used it as a prop in a shortfilm and it totally sells on-camera. Great way to keep it safe on set. Aside from the shortfilm it was easily worth it the money just to prank my friends. Super fun and would totally buy again!

It is what it says it very flimsy and cheap feeling. But you get what you pay for🤷🏼‍♀️

I recently purchased a knife online, and while overall I'm happy with the product, I was a little disappointed by one detail. I was under the impression that the knife was foldable based on the description and pictures, but when it arrived, I realized it was a fixed blade. The knife itself is still decent quality for the price—sharp, sturdy, and well-made—but I was expecting something more compact and portable like a folding knife. If you’re looking for a non-folding blade, this one will work great. Just be sure to double-check the product details if you're hoping for a foldable design! Still, it's a solid option for the price, so I'm giving it four stars.

Perfect for play fun

Junk!

Got these for my son. They broke super easily.
