Does the knife have a back spring in addition to the liner lock? I think that the video shows a non-assisted knife opened with a vigorous push of the thumb.
^Bingo. I'll bet that's it.
The MFH has a backspring; all one has to do, to get the blade to 'spring' to full-open, is to pivot the blade past the transition point of the backspring, after which the backspring will do the rest (it pulls the blade closed, or pushes it open, depending upon which end of travel it's nearer to).
I'd bet this is a standard-line knife, and using the thumbstud to force the blade past the transition is all that's needed. Lots of traditional slipjoints would behave the same way, with just the addition of the thumbstud and an agile thumb to get it moving.
If Case were actually marketing this, it seems odd there's no mention of it on their own mfr site, nor on the sites of their largest online retailers. Until I see it there, I'd assume this is more suitable for April Fool's day.
