not exactly the most fancy thing... and I still need to learn how to take it apart and clean it, but it's an automatic knife. I always wanted one of these.

I can tell you one thing about it, however, the spring mechanism is not powerful enough to even push the blade through a piece of corrugated cardboard. So this is not a stick it in a neck and kill type device. That would require a much more robust spring that probably would require some kind of wind-up doodle to load it strong enough to be able to cut through someone's throat or lungs.

I hope you enjoyed watching this thing go SNICK :)
