The CRKT Tailbone is a very small neck knife that fits nicely into all kinds of roles. It's got the strength of a fixed blade, but the footprint and convenience of a folder. The handle is wrapped with orange paracord, giving you a length of useful cordage in a pinch.
I got myself this knife because I wanted a small fixed blade. Little did I know, this particular knife has a suprise. I had no clue that it bends. The handle is made out of machine chain, which makes it bend. Somehow, though, it doesn't feel flimsy, and it's actually quite comfortable. The knife itself is good so far; it came razor sharp from the box, the sheath grips it very nicely, and the whole thing feels very sturdy even though it flexes. I can't wait to get out and use it.
As the other review mentions, this knife has a flexible handle (similar to a bike chain). This is just a terrible feature, and it wasn't mentioned in the description or indicated in pictures. The sheath doesn't have much retention either. I don't know why they would make it like this, it doesn't serve a function, makes it heavier and more complex to build.
