oxo makes a wonderful mango slicer. It cost 17 dollars or so (or perhaps 14)--but it is very much worth it to me. I love a good mango! They make it fun and easy.. much better than doing it by hand. you still have to separate the skin from each side, and this can be done either by using a vegetable peeler (or a sharp knife used in much the same fashion) or by slicing a grid into the mango half (being careful not to pierce the skin) and then turning the half inside out. The latter works best when the mango is somewhat ripe, but that's more a rule of thumb than a requirement. Enjoy!
