You know we love knives. But let’s talk –not only about a cooking tool– but about a historical and extraordinary knife embedded in Intuit culture and highly used in the modern kitchen.

We have no doubts that your kitchen may have a wide array of tools and equipment, from cookware to accessories like a proper cutting board and aprons. But, if you are looking to upgrade your kitchen knife set and equip your kitchen with the best of the best, an ancestral ulu knife is definitely worth your investment.

Derived from the Eskimo-Aleut term “ooloo”, the ulu knife was a device used by indigenous Alaskan tribes for thousands of years. Originally, it was named uuluurag, which meant a woman's knife. It has been traditionally used to clean the skins of different types of meat to make clothing and cut meat for different preparations.

In historical times, their blade was made up of everything from shale, slate, or quartzite with handles that could be made of wood, ivory, caribou antler, or even bone. Nowadays it contains a fine steel blade and its handle can be made of different ergonomic materials to best support culinary activities. Without a doubt, the ulu knife is still used in prestigious kitchens around the world. Let’s learn a little bit more about this transcendental culinary tool.

1. What Is A Ulu Knife?

An ulu knife is a curved knife of Eskimo origin. Several kitchen knives can be used to work with meats, such as a chef’s knife, a slicing knife, a butcher knife, or a cleaver knife. These are traditional knives but an ulu knife has a curved and thin crescent-shaped blade perfectly made to get the best results when cutting meats, vegetables, and many other ingredients.

2. Ulu Knife History

The Alaskan ulu knife has a history of more than 5,000 years. Starting with the Yupik, Aleut, and Inuit cultures in Alaska, Greenland, and Canada. It was created to be a knife for all purposes of typical day-to-day tasks of their communities. Originally, it was mostly used by women to skin animals and clean their meat before cooking, trim big chunks of ice, cut different foods, cut their kid's hair, and even as a weapon. 

Within time the ulu knife has crept into the mainstream market and it’s used in many kitchens around the world, nevertheless, its important role in Inuit culture remains just as important as it was when its invention, thousands of years ago.

One of its incredible perks is that the Alaskan ulu knife is disability-friendly. If a cook has any condition such as arthritis, nerve, wrist pain, carpal tunnel, or even partial loss of a limb, the ulu knife will provide the possibility of achieving kitchen tasks easily.

Historically, ulu knives were not only a tool but were used to be presented as gifts, because of their cultural symbolism. For example, if a member of their community accomplished a significant goal in education. Nowadays, the Artics Winter Games present gold, silver, and bronze uluit to athletes instead of medals.

The ulu knife comes in different sizes, styles, and shapes:

  • The size reflects its usage. An ulu knife with a 2 inches blade would be used for cutting patterns from animal skins (traditionally would also be used as part of a sewing kit). An ulu knife with a 6 inches blade or a 12 inches blade would be used for different purposes.
  • The styles reflect the way it’s designed. In the Alaskan style (also called Inupiat) the blade has a centerpiece cut out and both ends of the edge fit the handle. In the Canadian style, the blade is attached to the handle by a single stem in the center. In the West Greenlandic style, the blade has a triangular shape. And in the East Greenlandic style, the ends of the blade tend to be pointed.
  • The shape of the ulu knife ensures where the force of the blade is centered. This makes the ulu easier to use when cutting hard ingredients that contain hard objects such as bone. Because the rocking motion used when using an ulu knife pins down the food against the cutting board, which makes it easier to handle (unlike, when cutting meat we must support the cut by using a fork, for example).

      3. How To Use A Ulu Knife

      The ulu knife is used very simply. It has a strong handle that allows it to be implemented with one hand to facilitate the work for many cooks and to satisfy those who prefer to use only one hand to make cuts without much effort.

      Even if you are not an experienced cook, the Alaskan ulu knife is an incredibly versatile tool for you to get immersed in the culinary world. It can glide across ingredients and surfaces with ease and its curved blade stays sharp and intact for a long time without requiring ongoing maintenance.

      Although it was formerly used to clean animal skins and even to cut hair, today the best chefs use it to mince and dice vegetables like celery and onions, to cut meats like briskets, or fish and chicken, to cut big chunks of cheese and slice big plates of pizza, and to chop nuts like an expert would do!

      5. How To Sharpen A Ulu Knife

      The Alaskan ulu knife handles most household culinary tasks with ease and efficiency – from cutting soft ingredients like cheeses, fine produce like herbs and vegetables, to making thicker, sharper cuts on various types of meat, fish, and chicken. The increased cutting force and effortless motion and performance make food preparation fast and fun. This is an aspect that differentiates it from other types of knives that are usually for specific characteristics and tasks. 

      An important recommendation to keep in mind to ensure the longevity of your Alaskan ulu knife is to apply vegetable oil as needed to keep the handle moist. It's also important not to soak your ulu knife in water or any other cleaning solution. When cleaning the edge, you must be extremely careful to not cut yourself, and also, it’s recommended to use care around the edge to retain the sharpness of the blade.

      Nevertheless, all knives require sharpening, and in the case of ulu knives, these can be easily sharpened; allowing them to generate precise cuts every time without the need for equipment to keep them in their best shape.

      The ulu knife has only one thin edge, and that’s the only edge that should be sharpened when doing maintenance to your knife. According to Knife Planet, an ulu knife can be sharpened in just 10 minutes using a sharpening stone and a dull knife. Here are some simple steps you can follow to sharpen your ulu knife safely and correctly:

      1. Use a wet stone or 400 grit sandpaper (wet or dry) to sharpen the beveled edge of your knife
      2. Hold the knife by its wood handle firmly
      3. Apply light pressure and rotate the blade along the rock or the sandpaper. 
      4. If a burr appears while sharpening, use the surface of the rock –or the sandpaper– to gently remove it, don’t put much pressure on it. You can also use a leather strap if you have it.
      5. Once it’s fully sharpened, the edge should look well polished.
