For the price DEFINITELY WORTH IT
Bought these in 2021 for a short film I was working on. I needed a knife that didn't look like an obvious "fake knife" and found this on Amazon. Considering how cheap these are for barely $8, these are SUPER worth the price. They work exceptionally well despite constant use and fiddling with. Only one of them broke, but it only broke after quite a while of use. It's also pretty convincing as a real knife in dark lighting and with certain angles, evident by my short film. Because of the shape of the handle, you wouldn't really expect it to be a retractable knife either. OVERALL, considering you're getting 4 knives for so cheap, I'd certainly recommend them. Just don't expect SUPER high detail or realism past a glance.

Good quality for the price.
Great purchase, went to an airsoft game and handed these out to friends, plastic quality is to be expected, not bad not great, blade itself is a little loose but stays in the handle, weighs less than quarter of a pound. Great for movie props, airsoft games, or general fun at home.

Flimsy but looks good on screen
We used these as movie props and I’m glad they were a 4 pack. After using them for a while the spring started to get stuck. They feel incredibly flimsy but they look great on screen.

Fun Toy!
I got this to do the viral TikTok trend, and they did not disappoint! Results were hilarious. At first glance they look real. As for the quality, they're just okay. They sometimes get stuck and won't collapse in, which could cause minor injuries. They aren't sharp enough to do any serious damage, but it could hurt a bit. Also, they make a rattling sound when moved. For the price though, they are great and I'm definitely satisfied with my purchase.

Cheap garbage
Bought this product after reading some reviews I'm not sure if people have low standards or what, purchased for a few short movie scenes and was way under impressed as the blade doesn't even stay sturdy it wobbles around way to much and is very cheaply designed easy to see that its plastic on camera and flimsy just being held in the hand. do not buy.. will be returning all of them

Se ven bien pero...
En apariencia se ven casi como en la foto. El material es muy delicado y da la sensación de que no durará mucho tiempo. El resorte interno también se siente muy frágil, aunque por el precio quizá no se podría esperar más.
