Anyone know of a good pineapple core slicer or should I just use a knife? Seems like there would be less of a mess with a core tool even though there would be some wasted pineapple.
Unless you need perfect rings, a knife is faster, easy, and less waste. cut the top and bottom off, so you've got flat surfaces, make about a dozen cuts to get the sides off, cut in half length wise, cut the halves into quarters, and make a single diagonal cut to take the core off. If you need rings, cut it into slices instead of quarters, and take the core out with a paring knife.
You'd need to core an awful lot of pineapples for a single purpose tool to make sense.
