Although it's a very difficult trick to master, the "Suicide-Drop" trick is one of the flashiest and quickest open tricks that I know. If mastered this trick is one of the more impressive open tricks that is almost guaranteed to impress.
I did cut myself 3 times learning this trick that drew a small amount of blood. One in the palm, one on my ring finger and one on my middle finger. So if you're learning this trick I suggest that you safen your blade by putting scotch tape over it so you don't cut yourself.
I did the trick 3 times in this video; the second trick I over-snapped which caused the knife to snap out then quickly snap back in. I caught the closed knife but that's also failing. I was flawless the other two times and the last one is the clearest.
