While most people tend to cut a cake in wedges out of habit, this method yields portions that are often too large and awkward to slice. A better method is to cut the cake in a grid. This will give you more servings per tier and neater slices. Cut straight across the cake in 1-1/2 inch increments, and then cut each long slice into 2-inch portions so that you are left with pieces that are 1-1/2 inches by 2 inches by the height of the cake.
