The Ancient Arctic Knife That Still Works Brilliantly Today
The ulu knife is one of the oldest and most recognizable cutting tools in the Arctic world. Traditionally used by Inuit, Iñupiat, Yupik, and Aleut communities throughout Alaska, Northern Canada, and Greenland, the ulu has been a daily-use tool for thousands of years — and remains one of the most functional specialty knives available today.
According to the historical overview documented in the Wikipedia Ulu entry, ulus were used across Arctic communities for food preparation, fish and game processing, hide scraping, sewing preparation, cutting sinew, and a wide range of household and survival tasks. The design has remained largely unchanged for millennia — a testament to how well it works.
Museum collections at the National Museum of the American Indian and Arctic cultural archives document the ulu as one of the most important traditional cutting tools in Arctic Indigenous life — used daily by women and men across generations for tasks that sustained entire communities.
Why Is the Ulu Shaped Like That?
Unlike a traditional chef's knife, the ulu uses a curved blade with a handle mounted above the blade's center of gravity. This design is not decorative — it's functional. Placing the handle directly over the cutting edge allows force to be applied straight down through the blade, creating an efficient rocking motion that reduces wrist fatigue during repetitive cutting tasks.
The curved shape provides controlled chopping, smooth rocking cuts, one-handed operation, excellent leverage, and efficient repetitive prep work. Many modern cooks describe an ulu as a hybrid between a mezzaluna, a pizza rocker, and a chef's knife — combining the best elements of each into a single compact tool.
As Serious Eats has noted in its coverage of specialty kitchen knives, ergonomics and blade geometry matter significantly for repetitive cutting tasks — and the ulu's centered handle design distributes cutting force more efficiently than a traditional side-handle knife for rocking cuts.
Traditional Uses of Ulu Knives
Historically, ulus were practical all-purpose tools used throughout daily Arctic life. Traditional uses included skinning animals, cleaning fish, processing hides, cutting food, preparing furs, household tasks, and sewing preparation.
Regional variations developed across Alaska, Canada, and Greenland, with slightly different blade shapes, handle materials, and sizes adapted to local needs and available materials. Blades were historically made from slate, bone, or copper before metal became available through trade.
The McCord Museum holds significant collections of Indigenous Arctic material culture, including historical ulu knives that document the regional variation and craftsmanship of these tools across centuries. Additional historical and cultural references are archived through Library and Archives Canada, which documents Inuit material culture and traditional tool use across Northern communities.
Modern Kitchen Uses for Ulu Knives
Today, ulu knives are increasingly popular among home cooks, food enthusiasts, outdoor cooks, hunters, fishermen, and collectors. Modern kitchen uses include chopping herbs, mincing garlic, slicing pizza, cutting vegetables, cheese prep, sandwich preparation, and slicing cooked meats.
Outdoor users carry ulus for fish processing, camp cooking, hunting trips, and game cleaning — applications that mirror the knife's original traditional uses. Commercial ulu makers like The Ulu Factory in Fairbanks, Alaska — one of the most recognized sources for authentic Alaska ulu knives — and premium kitchen-focused makers like Lamson have expanded the market significantly. For outdoor and hunting applications, makers like Silver Stag produce ulus specifically designed for field use.
Why People Love Using Ulus
Many users find ulus fun to use, fast for repetitive chopping, comfortable during long prep sessions, visually unique, and easier for rocking cuts than traditional chef's knives. Food & Wine has covered the growing interest in specialty and heritage kitchen tools among serious home cooks — and the ulu fits squarely into that trend: a tool with deep cultural roots that also happens to perform exceptionally well in modern kitchens.
Why Ulu Knives Need Special Blade Protection
The same curved blade that makes an ulu useful also creates a storage problem that most knife owners don't anticipate until they own one.
Unlike straight knives, ulus rarely fit standard knife blocks — the slots are designed for straight blades and the curved ulu profile either doesn't fit or sits unstably. Magnetic knife strips don't work well either, as the curved blade doesn't sit flat against the magnet. Generic blade guards and sheaths are designed for straight knives and fail to cover the ulu's wide curved profile safely.
That leaves drawer storage — which knife-care experts consistently warn against. Better Homes & Gardens' knife storage guidance specifically recommends protecting knife edges from impact and loose storage contact, noting that blade-to-blade or blade-to-drawer contact damages edges and increases injury risk. For ulu knives, where the blade is wide and fully exposed, these risks are amplified compared to straight knives.

The Blade Guard® 6" Leather ULU Knife & Bench Scraper Sheath is purpose-built for the curved ulu blade profile. Crafted from genuine leather with reinforced stitching and a secure brass snap strap, it keeps the ulu blade safely covered during storage and transport.
- Purpose-built for curved blades — fits the ulu's wide curved profile that generic sheaths can't accommodate
- Genuine leather construction — durable, professional-grade protection
- Brass snap strap — secure closure keeps the blade covered during transport
- Reinforced stitching — built for long-term daily use
- Also fits bench scrapers — the same wide-blade storage problem applies to bench scrapers
Traveling with an Ulu Knife
Because ulu blades are wide and exposed, safe travel storage is especially important. Best practices include using a fitted blade guard or sheath, storing inside padded compartments, avoiding loose bag storage, and transporting only in checked luggage during airline travel — never in carry-on bags. A leather sheath like the Blade Guard® ULU Sheath makes travel significantly safer — the brass snap keeps the blade covered even if the bag shifts or is handled roughly.
Why Ulu Knives Continue to Grow in Popularity
Modern buyers are drawn to ulus because they combine cultural history, artisan craftsmanship, kitchen utility, outdoor versatility, and gift appeal in a single tool. An ulu is not simply a novelty knife. It is a centuries-old cutting tool that still performs exceptionally well in modern kitchens and outdoor environments — and one that carries a cultural story worth knowing.
Frequently Asked Questions
What is an ulu knife used for?
Ulu knives are used for chopping herbs, mincing garlic, slicing pizza, cutting vegetables, cheese prep, and cooked meat slicing in modern kitchens. Traditionally, they were used for skinning animals, cleaning fish, processing hides, and a wide range of household tasks in Arctic Indigenous communities. Outdoor users carry them for fish processing, camp cooking, and game cleaning.
Why won't my ulu knife fit in a knife block?
Standard knife block slots are designed for straight blades. The ulu's curved blade profile doesn't fit safely into straight slots — it either won't insert fully or sits at an unstable angle. A purpose-built ulu sheath is the correct storage solution.
How do you store an ulu knife safely?
The safest storage for an ulu knife is a purpose-built leather sheath designed for the curved blade profile. Drawer storage without a sheath risks dulling the blade edge and causing injury. Magnetic strips don't work well because the curved blade doesn't sit flat. The Blade Guard® 6" Leather ULU Sheath is designed specifically for this purpose.
What's the difference between an ulu knife and a mezzaluna?
Both use curved blades for rocking cuts, but they differ in design and origin. A mezzaluna typically has two handles at either end of a curved blade and is used with two hands. An ulu has a single centered handle mounted above the blade, allowing one-handed use. The ulu also has a much longer cultural history, originating in Arctic Indigenous communities thousands of years ago.
Can you use a regular knife sheath for an ulu?
Standard knife sheaths are designed for straight blades and don't accommodate the ulu's wide curved profile. A generic sheath will either not fit at all or leave portions of the blade exposed. A purpose-built ulu sheath is designed to fit the curved profile correctly.
Is an ulu knife good for everyday kitchen use?
Yes — for specific tasks. Ulus excel at herb chopping, mincing, pizza cutting, and any task involving a rocking motion. Many cooks keep both a chef's knife and an ulu for different tasks.
What is a bench scraper sheath?
A bench scraper sheath is a protective cover for the wide, flat blade of a bench scraper. Like ulu knives, bench scrapers have wide blades that don't fit standard knife sheaths. The Blade Guard® 6" Leather ULU Sheath fits both ulu knives and bench scrapers up to 6 inches.
