New Extrema Ratio Folders: What's the lock?

Any inside info on 'em?

They look a lot more hand-friendly and functional. Maybe these were designed to be more EDC-able than the previous ones. Notice the deep-carry clip? Just wondering what the heck is the lock type supposed to be? Looks like a liner with a secondary lock?

Looks like a liner lock with some sort of "LAWKS" system like CTKT?

Though so too but seems to me (it is 2:00 AM over here) to be a disadvantage if you're a typical right-hander to engage it?? What really impressed me about them was their "OMG"-strong lockback, the lock-type I like albeit more scaled down.
