I have 2.
It's okay as a money clip. Not horrible, but not a great shape as a clip to hold bills as its too thin with a short clip, so the bills sort of just hang, or for the pocket, as a clip, as again it's too thin and becomes awkward coupled with bills in the pocket. It also gets lost a lot as its polished and slippery like a pebble, which would be the best comparison.
I find it to be the worst clip out of the money clips I have when I do use one, including money clip knives. And yeah, it works better just as a knife using the clip as a pocket clip. More knife then clip.
