I needed a knife that didn't look like an obvious "fake knife" and found this on desertcart. 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. Review: 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. ## Features - You Will Get: you will receive 4 pieces retractable fake knife in the package, they will make you the magician and prankster in the party, that everyone will be able to join in on the fun - Size and Material: retractable prop knife and handle are approximately 8.27 inch/ 21 cm long; Made of obtuse plastic, plastic blade retracts into the handle, blade disappears into handle, will do no harm on human body - Magical design: the disappearing dagger features a small plastic knife with spring loaded retractable blade which slides into the handle and slides out again when you pull away, your friends will be shocked by this little gadget novelty toy - Suit for: funny gag toy for fancy dress, Halloween, April Fool's Day, theater props, school play, tricks or jokes and any other funny occasions and costume events, you can take them out whenever you need a laugh or distraction, but not suitable for children under 14 years of age - Interesting gift: they are cute and very portable, everyone will love getting this fun retractable knife, they can make for a good small prize or Easter egg, you can fool your friends and make them laugh by playing this fake dagger ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07VK7KGH4 | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #17,922 in Toys & Games ( See Top 100 in Toys & Games ) #138 in Gags & Practical Joke Toys | | Blade Length | 21 Centimeters | | Blade Material | Plastic | | Blade Shape | Straight | | Blade Type | Fake | | Brand | Boao | | Brand Name | Boao | | Color | Black | | Customer Reviews | 4.2 out of 5 stars 2,268 Reviews | | Hand Orientation | Ambidextrous | | Handle Material | Plastic | | Included Components | Blade | | Is Product Cordless | Yes | | Item Length | 8.27 Inches | | Item Shape | Straight | | Item Weight | 0.22 Pounds | | Manufacturer | Boao | | Part Number | Boao-Knife Toy-01 | | Product Care Instructions | Hand Wash Only | | Recommended Uses For Product | Fancy dress, Halloween, April Fool's Day, theater props, school plays, tricks or jokes, costume events Recommended Uses For Product Fancy dress, Halloween, April Fool's Day, theater props, school plays, tricks or jokes, costume events See more | | Reusability | Reusable | | Set Name | 4-Piece Set | | Size | 8.27 inches | | Special Feature | Retractable | | Special Features | Retractable | | Style | Modern | | Theme | Fantasy | | UPC | 760385951112 | | Unit Count | 4 Count | ## Product Details - **Age Range (Description):** Adult - **Blade Length:** 21 Centimeters - **Blade Material:** Plastic - **Brand:** Boao - **Color:** Black - **Handle Material:** Plastic - **Included Components:** Blade - **Special Feature:** Retractable - **Style:** Modern ## Images ![Boao 4 Pieces Retractable Fake Knife Retractable Prop Knife False Trick Joke Gadget Toy Disappearing Dagger Fake Plastic Blade for Halloween Costume Fools Day Party - Image 1](https://m.media-amazon.com/images/I/71t0FUaP29L.jpg) ## Available Options This product comes in different **Number Of Items** options. ## Questions & Answers **Q: Can you close it?** A: No, they don’t close. **Q: how much pressure does it take to push it in?

All four knives are very functional. He plays with these knives constantly so I would expect at least one of them to malfunction.
