I had the opportunity to really check these out at Blade.
They are really advanced in the construction, the backspacer and lockbar are machined from billet ti, with the backspacer having a cutout through which the flipper tab "flies through" and eventually becomes the blade stop. Hard to describe.
The handle is 3d machined CF. Anyone here ever machined CF or even talked to someone who has? It's not easy.
The cutout in the blade with the carbon filler is a styling queue and another opportunity to showcase production capability.
I don't see any other companies making anything that comes near the 999 in terms of stacked variances and engineering technology.
Remember, this design was submitted at Blade in the American Knife of the Year category, which many of you might be surprised, IT WON in 2015.

I am hoping I am lucky to score one, and I will use it just as I do all my knives. Some will buy just to flip, but that is life in the big city.
Pictures from Blade 2015 - and I apologize, it's hard (at least for me) to get good pictures there -
Now to go check my emails to see if I got the newsletter!
