Finding The Best Kitchen Knives

When You Go To Certain Japanese Restaurants When Chefs Perform For You, Are They Specially Trained For That?

Usually the restaurants are "Hibachi Steakhouses" were you sit at a table with the chef cooking your food in front of you. He does tricks like flipping knives and doing things with fire.

Is there a separate school where they teach this? Do these chefs need a special certification or license to be able to do this?

Does anyone know?
