As Frank said, Moki doesn't make crap. The same factory makes or has made knives for Spyderco, AG Russell, Kershaw, Al Mar, and others. Moki knives themselves are widely regarded as being near-custom quality. Most commonly recommended and owned here is their Fish Owl knife, a simple micarta handled lockback. Everybody that owns one (myself included) can't say enough good about them. Heck, even the nylon sheath and box they ship in are uncommonly nice.
As for the Colon, it's up to you whether it's a proper knife or just a novelty. A 3/4" blade is of rather limited usefulness. Then again, I on occasion wear a Spyderco Police necklace (titanium handles, ATS-34 blade, too small to be of use), so if you like it, why not get one? You can be assured it'll be of excellent quality.
