Ice Pick

This special type of metal awl is used to break holes in frozen lakes for ice fishing and to chip away ice chunks when building snow houses. (Note, however, that the Snow Blade, or iuak, described below, is the primary tool for such a job.) Consisting of a bone or wood handle and a sharp metal point about six inches long, an ice pick also can be used as an impaling weapon.
