As far as I know there are only three styles of eating: hands, chopsticks, knives and forks (spoons are universal).
And if you had to categorize what to eat with what, it would be
Hands: most indian food, fast food
Chopsticks: Oriental, South East, Asian, Japanese
knives and forks: most of the western world
So I find it pretty funny when people try to eat Indian breads which are flat and non porous with knives and forks. The forks don't pierce very well, the knives don't cut very well because the structure of the bread is different. It's all great to appear well educated in table manners, but I'll stick to my hands. Certain things are made to be eaten in a certain way.
