I have two iKon OC Bulldogs: a version 1 and a version 2. They are very, very similar-looking. But version one gave me massive irritation while giving a very close shave. It wasn't finished as well at the teeth and the teeth were the problem - they were somewhat sharp themselves. Version 2 was supposed to be an improvement, and that's exactly what I found. Still a very close shave - probably the closest of any DE I've had. But the irritation problem had been licked. The teeth were not sharp any more. Both versions have been discontinued. Supposedly a new version is being developed, and the maker is discontinuing the technique of machining the parts from solid aluminum and changing over to making the razors parts from a mold. So, version 1 was a bust for me and version 2 is my best razor. "LeisureGuy" (author Michael Ham) is also very high on his iKon, and I'm guessing (but can't confirm) it's a version 2 also.
