How do you cut a pineapple?
with a knife You chop off the leaves, then peel off the skin. Next you have to core it and slice it into rings (If you want to). Or, alternatively, you can buy a pineapple slicer which takes off the skin and turns it into a long spiral.
First, place the pineapple long ways on a cutting board. Then slice off each of the ends, the top and the bottom. Then set the pineapple vertically. Slice off each of the sides. Make sure to cut enough so the "eyes" of the pineapple are removed. After this, cut the pineapple in half, then half again. Remove the core of the pineapple and then cut into small pieces. Enjoy!

Cut pineapple lasts a couple of days if placed in a tightly covered container and stored in the refrigerator. (emphasis added) Therefore, whole pineapple 2-4 days, cut pineapple 1-2 days.
