The Inuit traditionally use sod to construct their dwellings because the tundra’s harsh environment prevents tree growth. An
ulo (normally spelled
ulu) is a thin, fan-shaped knife with a handle made from antler, horn, or ivory and a blade made from slate. Traditionally, Inuit women used the
ulo for a variety of purposes, including skinning and butchering animals, cutting hair, and shaping ice and snow for igloo construction.
