I will start with what I liked. I backed the Kickstarter, and received my knife very quickly. I like the weight and compactness of the knife and sheath. I can clip it inside my pocket like a folder and not even notice it's there. The ferro rod throws a lot of sparks.
The handle is a little small, and can get uncomfortable in my hands, but that may be just a personal preference. My biggest complaint is that I bought it to use it as a boot knife, and within a week of wearing it that way, I noticed that the sheath had somehow gotten looser around the blade, and now it was rattling. Not that the blade could fall out, it was very firmly held in the sheath. But the knife could "wiggle" inside the sheath, causing it to rattle. Not sure how this happened.
Overall, a nice companion knife to take with you instead of a folder, with some very good features.
