Use a very sharp knife. Having a sharp knife will help you to cut your ham in thin, perfect slices. Be sure the knife is long enough to cut through the width of the ham and use long smooth strokes to slice the ham more easily.
The key to carving a ham safely and successfully always starts with the right tools. The best fork to use is a chef’s fork. It has two long tines and measures about 11 inches long, with a handle that features a base to rest your forefinger and thumb. Whether you’re left or right-handed, a chef’s fork is a great tool for holding the meat down while you slice with your other hand.
If possible, use a chef’s knife for this. It has a long blade, usually measuring between 8 and 14 inches. It is the perfect tool for easily slicing through ham.
Only carve the ham that you need to serve. Leave the remainder on the bone so that it stays warm and retains more of its juiciness. Be sure to hang on to the ham bone and any scraps. You can use them to make a delicious soup. [2] X Research source
Spiral sliced hams come pre-sliced, with each slice about the same in thickness. There are generally three basic cuts needed in order to remove the slices from the bone.
