How fast can you open a knife?

I was bored last night, so I decided to do a time test to see which knife can be opened the fastest. This test is done on a balisong, a flick knife and and auto knife

.
The balisong took around 2 seconds to open due to the flipping and you need to capture the handle.

The flick knife took around around 1 second to open

The auto also took around 1 second to open.

Comment - I would say between the flick knife and the auto, I would rather choose the flick knife cause it totally depends on the movement of your wrist and not some spring that can jam.
