Here a good video clip of Vinny Balsamello fighting in the Shidokan International Championships in Japan. It is bare knuckle full contact fighting, similar to Kyokushin. Actually it was more like what Kyokushin was like when it started (now there are no grabs, throws, clinch allowed). Anyway, the fighters are allowed a brief clinch, throws and a few seconds allowed for a quick submission on the ground. Some will ask, why are there no face punches? Sure it would make a difference, but with the grabbing of the Gi and the use of throws it would still be similar to what is seen in the video. There is a lot of information out there where there Karate guys telling you how to apply traditional techniques to real fighting. Don't believe 'em. This is what it would be like.
