Behold the Magic "Sneaky Stabber" – a plastic knife that’s all bark and no bite! With a clever dual-spring mechanism hidden in its handle, this mischievous blade looks like it’s plunging into its target, but it’s secretly retreating inside. Then, with a cheeky spring-loaded comeback, it pops right back out, ready for its next faux attack. Perfect for pranks, props, or just confusing your friends at the dinner table!

Requires 2 compression springs 10mm x 50mm Can be found at any hardware store or Harbour Freight has a Spring Assortment kit. 
Also a dab of your favorite adhesive to hold the guard on after installation of the springs and blade.
