Using a sharp knife, slice down the length of the pear to create two halves.
Use a small spoon or melon baller to scoop out the core.
For stuffed pears — scoop out a bit more to create a cavity large enough for the stuffing.
For sliced pears — lay one half of the pear on a flat surface, cut side facing down. Slice lengthwise from top to bottom of the pear in as thick or thin a manner as desired. For shorter slices, slice horizontally across the pear.
For chopped or diced pears — cut around the core so that there are four pieces of pear. Lay a flat side of one of the pieces down on the cutting board and slice into 1/4 -1/2" thick pieces. Turn the slices at a 90 degree angle and slice in the opposite direction for chopped pears. To create a smaller dice, simply make thinner slices and cuts.
