What is the easiest way to carve Ivory?

The easiest way to carve ivory is with a moto-tool fitted with a carving bit, but hand tools that are used for hard wood (such as whittling knives, chisels, saws, drills, scrapers) can also be used. What tools will be best to use will depend on:

the type of carving (sculpture in the round, relief, scrimshaw)

the hardness of your ivory,

the finish you want to achieve (smooth, hand hewn),

the purpose of the carving (artistic, decorative, religious, functional).
