A serrated knife and a paring knife are the tools needed to cut a pineapple. A cutting board is also needed when slicing a pineapple.
The serrated knife is used to cut off the top and bottom of the pineapple. This knife is then used to cut off the skin in long strips. The paring knife is used to remove any remaining eyes or prickly parts of the fruit.
An apple or cookie cutter can be used to remove the core from pineapple slices. The serrated knife can be used to remove the core when it is to be sliced in chunks.
Pineapple slicers and cutters are available where most kitchen accessories are sold, but they are not necessary.
