The pros at the raw bar make it look easy, but it's all about technique—specifically, the precision placement and leverage of your oyster knife. You will need: fresh oysters, any type, lots of ice, a small brush, an oyster knife, a cutting board, a towel, a wide shallow bowl or platter, lemon wedges, oyster glove and cocktail sauce. Tip: When you are rinsing the oysters, throw out any that are slightly open and don't spring closed at your touch.
