Benchmade 665, New lock?

Anyone see the description of the new benchmade 665 on bladehq? It says it is a push button assist knife, curious how that would work and not be an auto.
 
It isn't an auto as it opens just like any other BM Axis assist knife (i.e. push the thumb stud and at a certain point the assist spring engages and opens the knife). Benchmade describes the button on the side as part of their new "Amibextrous Push Button" which disengages the lock that keeps the blade from closing. They said on their website that it is about as strong as the axis lock. There is also a safety on the spine that can lock the blade in the closed position (like a current Barrage or Volli).

I bet it will be fun to flick open and closed once the assist is removed. Can't wait for some reviews on how it stacks up against the Axis lock. I like the knife but not a fan of the blue black G10 or the spine lock.
 
According to Benchmade design engineer, it is brand new lock mechanism. Still have to pushup thumb stud as a part of "not auto" law.
 
TechDoc, are you sure there's a safety on the spine? I wonder if the safety is essentially incorporated into the lock mechanism. In that scenario the button lock has to be depressed while pushing the thumb studs (at least until the coil spring assist engages). That would address the only issue I've seen with the Barrages sometimes springing when dropped on the floor (yes - I fumbled mine a couple times and had that happen). Not that that has ever been a big issue, but companies have to always look at liability. We live in a lawyers world.
 
ToolDiva, what you describe is what I was thinking initially but Jason, the BM design engineer on their forum, said otherwise. The button is not used at all when opening the knife. He said there is a spine safety that can lock the knife closed.

The button (actually buttons since there is one on each side) is only used when closing the blade. You have to push the button to unlock the locking mechanism to close the blade. The way he described it it seems to function exactly like an axis lock (i.e. something you have to slide to close the blade but don't have to touch to open the blade). But he said the internals are different from the AXIS design.

I don't have any special insight, I am just going off of what has been posted in this thread.. And the spine safety is clearly visible in the knife picture and was confirmed by Jason.

TechDoc - ok, thanks. I see the safety in the picture in the thread you linked.

It'll be interesting to see how this lock works. Wonder if this will be primarily for assisted models.

Overall, I'm more impressed with this year's lineup than last year's releases. Seems like Benchmade is being a bit more creative and taking some risks by moving out of their comfort zone.
