How gory is the movie "Cube"?

I want to see the movie Cube, but I know that the Saw movies were very heavily inspired by it, and I'm not really in the mood to watch something that incredibly gory. A little bit of gore is fine, but how gory is Cube? I also want to watch it with my dad, but he is very squeamish, and is totally grossed out by anything with razors. Please don't give any spoilers, but is it really gross, and is there anything involving straight razors?
