Novelty rather than tool
This product (I don't even want to call it a 'knife') is just a novelty rather than a potentially useful tool. The bizarre opening and shutting gimmick makes it totally impractical and frankly irritating. Deployment is slow and laborious, with the four frictiony pivot points requiring a lot of force to get through the totally non-intuitive motions. Closing is even worse, with the tiny double liner-lock (technically, but not what you are imagining) creating genuine jeopardy as you try to compress them while not closing the blade on your fingers. It's also grossly overpriced for something so useless, although I don't doubt that the manufacturing costs are high for such a unique item. It's possible that its big brother makes more sense, since the design is intended to give you the longest possible blade with the shortest possible handle. In the case of the Nano, it just means that the handle is, if anything, too short. If you remove the pocket clip, as I always do, it leaves you with a bolt sticking up from the handle, which is almost as irritating as the clip itself. As it happens, I like weird knives, so I don't totally regret the purchase; but if you want a knife which is potentially useful, this is one to avoid.
