Three ulus

Inuit women use a crescent-shaped knife, the ulu, in most aspects of food and skin preparation: for skinning animals, preparing skins, butchering, eating, and sewing. Different kinds of ulus are used for different purposes:

'The smaller ulu are only for cutting patterns, - they are too small to use for skin preparation. To prepare skins, I usually use the ones that get sharp easily, or the ones that are sharp, that is the way I know it. The largest ulu is the one that removes the blubber from a skin ....'

Today, ulu blades are usually made of sheets of stainless steel or saw blades. In the past, slate was the material most commonly used.

'There is a stone called uluksarnnak, this was used for ulus. The blade was grounded to thinness; as you file away the stone, you would look up the blade to see if the light is coming through, and when that happens, it is thin enough ... It was said that someone was given a knife, most likely when people were just being introduced to imported goods. This man was given a knife, and he proceeded to sharpen it. He would hold it up to see if the light would go through it, but the light would not go through. So he said: 'Ipiksijunnanngittualuk una' ('This cannot get sharp'). At once he ran the blade through his hand, it went right through.'
