Fun little knife
Overall I’m very happy with this knife. Blade shape is useful, opening is easy, and it feels decent in hand for how small it is. Only two things I don’t like - first, the lock is small and difficult to open, making putting the knife away a two hand operation. Second, the pocket clip is not deep carry, so a decent chunk of the knife stick out from my pocket.

Cons: Lock Ease of Use
Not bad, not perfect.
Like the design and it has a snappy action. Nice weight for its size. Pocket clip is nice and secure. Frame lock is somewhat difficult to safely operate one-handed on a knife this small (and I have smaller fingers than most). Edge grind on the "tip" of my particular knife wasn't completely even.

Leaves a lot to be desired
It’s still a nice and compact edc knife, but the blade is not assisted and the bearing is very stiff. As the other reviewer said, the edge on the blade and point isn’t even and will definitely need some work as well. The pocket clip is a bit bulky and doesn’t carry as nice as something of this low profile should. It doesn’t feel like a $55 knife, let alone an $80 one, but it is what it is.

nice to look at, not so good to use
I picked this up because I saw the magic words "you can pry with it" on a different seller's site. It does look and feel sturdy enough to actually use it for that purpose in a pinch. My example is not a good cutter at all. It's not very sharp, but I think the blade geometry is the bigger issue. It's very thick in the middle of the blade, giving it that pry bar vibe. That profile generates too much friction. It's ok for cutting the tape on a box, but not good at actually breaking the box down. There are some flaws in the design. It seems like this knife was just meant to look cool and not to be a functional tool. It may the the Cybertruck of the knife world. 1) The pocket clip is the extreme opposite of deep carry - instead of being folded over, it's a flat piece of metal sitting on a metal block. There's no way this really tiny knife is getting clipped to your pocket without leaving half an inch hanging out. 2) There is jimping on the top front of the blade, like it was meant to be a front flipper. I think it probably would front flip, except that there is on relief on the handle to let your finger actually reach that jimping! It even has jimping on the "top" of the closed blade, where it is completely inaccessible with the blade open. 3) There is no relief in the presentation side to give your thumb access to the frame lock, nor is there any jimping on the top of the frame work to give any grip. Makes it very hard to operate the lock. 4) There is an unsharpened edge on the top of the blade - not sure if that's a Scandi grind or something else, but I'm pretty sure it's just there to look stylish. I guess it reduced weight, but if you cared about the weight, why clamp a block of steel to the side to make a bad pocket clip?
