Amazing little auto!
Ian T.
Love the full handle size with the small blade. It does simple everyday tasks with ease without scaring the sheeple and looks amazing with the brown g10 inlay (which has a pretty grippy texture) and satin blade. Super smooth and snappy action on it. I thought my Kershaw Launch 4 was fast, this thing flies open!

-Small blade with a nice sized handle.
-Smooth and fast action
-Slim and lightweight
-Looks great! You could almost even consider it a "gentleman's auto"
-Very deep pocket clip, it just disappears.
-Hair shaving sharp out of the box.

-Wish they would have used torx screws instead of Allen screws.

Thank you Protech for this gem.
