This is one of the best lock ups in the knife world today. Hopefully we see CRKT make an s35vn version!
Very good innovation for this price point

I like this knife a lot - really well styled, with very smooth opening - it's better with the flipper than it is with the thumb stud. Blade is reasonably sharp and is imposing when it is fully opened. The G-10 on the handles is good and allows for good retention of the knife. I like the concept of the deadbolt quite a bit, and it will become a CRKT classic much as the field-strip feature has become iconic. There is a little bit of stiffness in the deadbolt, but I expect it will smooth out with age and use. And I'd rather have the closing a little delayed vs. the opening. Looks good, feels good, nice knife. Probably 4.5 stars, but I rounded up.
A large knife, but just so wonderful in hand!

Love the Deadbolt locking feature! Gives me a very sound peace of mind to know it will not close unless I want it to. The button is easy to use, and feels very natural when closing the knife. The blade is very thick, and feels like I can put this knife through a lot of hard work and not have to worry about hurting it no matter what I put it through.
The thumb relief in the scales is a great touch that makes this knife feel extra secure in your hand. And I love the deep carry pocket clip to keep this large knife hidden in your pocket, and out of the way. It doesn't feel like a large knife in your pocket, and you can easily put your hand in your pocket and retrieve your keys without out it getting in your way. When I first got it, I was like, woah..Thats a big knife. But after just one day of carrying it, I completely forget about it because of how it carries so easily tip up in your pocket.
The other reviewer talks about how the button used to close the knife is very rough and hard to push, I didn't find mine to be like that at all. It gives a very noticeable click when you push it in, and lets you know when the locking mechanism is disengaged. Easy to push in, and feels very secure.
As for such a large blade, it's really impressive to be able to so easily open it with either the thumbstud, or with the back flipper. It just glides so smooth. Super happy with this purchase, and will be very happy to carry this knife every day!
