How to Cut a pineapple in an artistic and less wasteful way

This video showcases the skills of the demonstrator in cutting a pineapple in an artistic manner. He begins by removing transverse sections, one each from top and bottom with a sharp knife. He then cuts off the remaining skin vertically in eight thin sections to keep wastage to a minimum. He marks off oblique lines one above the other all along the periphery. He cuts off very thin and small oblique slices along the marked lines, rotating the pineapple slowly. The resulting shape is now like a saw. He now cuts off circular slices which appear star-shaped and also some half or quarter slices, all of which appear very artistic.
