ZJoey 9 Pack Retractable Fake Knives – Trick Plastic Blades for Pranks, Halloween, April Fool's

This 9-piece set of ZJoey retractable fake knives gives you a handful of trick props that look convincing but are made entirely from plastic. Each blade slides into the handle when pressed and springs back out when released, so no one gets hurt. Great for Halloween costumes, April Fool’s gags, cosplay, and amateur filmmaking.

What Comes in the Package

You receive 9 individual trick knives in the 9 Pcs Style F configuration. Each knife measures between 7 and 8.29 inches long, with a 9-inch blade length as listed. The handles are black plastic with an embossed texture for a secure grip. All pieces are the same style, giving you a uniform set for group pranks or multiple hands.

Material and Build Quality

The plastic used is non-toxic and durable, with a smooth finish free of burrs. The handle is comfortable to hold, and the blade retracts fully into the handle. The spring mechanism causes the blade to pop up automatically when you let go, which is the core gag effect. Because there is no metal, there is no risk of cuts or punctures.

How the Retractable Mechanism Works

Press the tip of the blade against a surface or simply push it in with your hand and it slides into the handle. As long as you hold it in, the blade stays hidden. The moment you release pressure, an internal spring pushes the blade back out, making it look like a real knife appearing. This allows for convincing stabbing motions without any actual harm.

Are These Knives Safe for Pranks?

Yes, because the entire knife is plastic and the blade retracts. The intended use is for humor, not as a weapon. However, note the age recommendation: the set is not suitable for children under 18. Adults and teens can use them confidently. The mechanism is simple and reliable, but it's always wise to avoid swinging or throwing them.

When to Use These Props

These retractable knives work for Halloween costumes, April Fool’s Day pranks, magic shows, cosplay events, school theater productions, short films, and party games. They can also serve as practice tools for stage combat or acting. The 9-pack ensures you have enough for a group scene or multiple attempts.
