Elbow witches are old women with awls in their elbows in the Ojibwa story of Aayaase (also known as "Aayaash" or "Iyash"), "Filcher-of-Meat". Blinded by cooking smoke, the sisters killed each other in their attempts to kill him for their meal.[1]
Elbow Witch is Monster in My Pocket #63, one of only three monsters derived from Native American mythology, the others being Wendigo and (to an extent) Bigfoot. The character's awls look very much like tusks.
