Rotating the handle of this knife clockwise winds an internal spring.
This spring quickly turns a removable shaft along the top edge of this knife which in turn spins a flexible metal 'foot' at the tip, held in place with a mousetrap-like catch.

Making the first chop releases the spring and the length you've preset the foot determines just how high the knife will bounce after the initial chop.

I can't decide if this is a really good bad idea, or a really bad good idea.

Does it have a kind of semi-automatic mechanism for repeated recoil chopping, or are you thinking more of one mighty recoil? Could it be plugged into mains power or stronger recoil? Or perhaps have a small 2-stroke engine built into the handle?

I thought this was going to be an idea about a stabbing knife that springs back into its holder after penetrating some unfortunate victim up to the hilt.

I was glad it wasn't.
