Understanding How an Ulu Knife Works
An ulu knife cuts differently from a standard chef's knife. Instead of slicing forward with a pointed blade, the ulu uses a curved edge and a rocking motion. The centered handle places force directly above the blade edge, creating efficient downward chopping power with minimal wrist strain.
This design has been used for centuries throughout Arctic Indigenous communities for food prep and practical daily work. According to the Wikipedia Ulu entry, the ulu's handle-above-blade design was developed specifically to maximize cutting efficiency for repetitive tasks — a principle that translates directly to modern kitchen use.
Understanding the mechanics before you start makes the learning curve much shorter. The ulu is not a difficult knife to use — but it rewards a slightly different technique than most cooks are used to.
Best Foods to Cut with an Ulu Knife
Modern users commonly use ulus for herbs, onions, garlic, pizza, cheese, vegetables, cooked meats, sandwich prep, and nuts. The curved blade excels at repetitive chopping and controlled rocking cuts — tasks where a traditional chef's knife requires multiple long strokes, the ulu handles in a compact rocking motion.
Outdoor users often use ulus for fish cleaning, game processing, and camp cooking — applications that mirror the knife's original traditional uses in Arctic Indigenous communities, as documented by the National Museum of the American Indian.
Commercial ulu makers like The Ulu Factory in Fairbanks, Alaska — one of the most recognized sources for authentic Alaska ulu knives — note that pizza cutting and herb chopping are among the most popular modern uses for their knives. Premium kitchen-focused makers like Lamson similarly position ulus as specialty tools for rocking cuts and repetitive prep work.
Basic Ulu Rocking Technique
Step 1: Secure the Cutting Board
Always place the cutting board on a stable, non-slip surface. A damp towel under the board prevents sliding. For ulu work, a wooden bowl (often sold with ulu sets) provides a curved surface that matches the blade's arc — ideal for herb chopping and mincing.
Step 2: Grip the Handle Firmly
Hold the centered handle comfortably with your dominant hand, keeping fingers away from the blade edge. The handle sits above the blade — your grip should feel balanced and secure, not awkward. If it feels unstable, adjust your grip position along the handle.
Step 3: Use a Rocking Motion
Rock the blade forward and backward while applying steady downward pressure. The pivot point is the center of the blade's curve. Keep the motion controlled and rhythmic — the ulu is designed for efficiency, not force.
Step 4: Let the Curve Do the Work
Avoid excessive force. The blade geometry is designed to cut efficiently through motion and leverage. As Serious Eats notes in its coverage of knife ergonomics, proper technique with a well-designed blade requires significantly less effort than forcing a poorly-suited tool through the same task.
Why Some Cooks Prefer Ulus
Many users enjoy ulus because they reduce repetitive wrist motion, feel compact and controlled, allow fast herb chopping, work well in smaller prep spaces, and create smooth rocking cuts. For pizza, herbs, and vegetables, many cooks find ulus surprisingly efficient once they've learned the technique.
Food & Wine has noted the growing interest among serious home cooks in specialty and heritage kitchen tools — and the ulu's combination of cultural history and genuine kitchen utility makes it one of the more compelling additions to a well-equipped kitchen.
Safety Tips for Ulu Knives
Because ulus have broad exposed cutting edges, safe handling matters more than with narrow-bladed knives. The wide curved blade covers more surface area than a standard chef's knife, which means the margin for error during handling is smaller.
Important safety practices:
- Never leave an ulu loose in a drawer. The wide exposed blade creates injury risk for anyone reaching into the drawer, and blade contact with other utensils dulls the edge quickly.
- Use a fitted blade guard after every use. A purpose-built sheath keeps the blade covered between uses and during transport.
- Keep fingers clear of the cutting path. The rocking motion covers a wider arc than a straight knife — be aware of where the blade travels.
- Store safely after each use. Return the ulu to its sheath immediately after washing and drying.
- Transport with blade protection. Never carry an ulu in a bag without a sheath.
Why Proper Storage Matters
Curved blades create unique storage challenges that most knife owners don't anticipate until they own an ulu. Standard knife blocks often fail to fit ulus properly, leave edges exposed, or create awkward insertion angles. Loose drawer storage chips edges, dulls blades, and increases injury risks.
Better Homes & Gardens' knife-care guidance warns specifically against unprotected drawer storage because blade contact damages knife edges over time — a risk that's amplified with ulu knives because the wide curved blade has more exposed surface area than a straight knife.
The correct solution is a purpose-built ulu sheath. The Blade Guard® 6" Leather ULU Knife & Bench Scraper Sheath is designed specifically for the curved ulu blade profile — genuine leather, brass snap strap, reinforced stitching. It fits the wide curved profile that generic sheaths can't accommodate, and also fits bench scrapers up to 6 inches.
How to Sharpen an Ulu Knife
Most ulus can be sharpened using whetstones, sharpening rods, or guided sharpeners. The key is maintaining a consistent edge angle along the entire curve of the blade — which requires more attention than sharpening a straight knife but is not significantly more difficult with practice.
Sharpen carefully along the entire curve while maintaining consistent edge angles. Work in sections if needed, moving from one end of the curve to the other. A leather strop after sharpening helps align the edge and extends sharpness between full sharpenings.
Proper storage in a fitted sheath between uses significantly reduces how often sharpening is needed — blade contact with drawers, other utensils, and hard surfaces is the primary cause of edge degradation between uses.
Traveling with an Ulu
Ulus should never travel loose inside luggage or kitchen bags. The wide exposed blade creates injury risk during packing and unpacking, and unprotected blade contact with bag contents dulls the edge quickly.
Best travel practices: use a curved blade guard, store inside padded compartments, avoid exposed edge contact with other items, and protect the blade during transport. For airline travel, ulus must be transported in checked luggage only — never in carry-on bags. A fitted leather sheath like the Blade Guard® ULU Sheath keeps the blade safely covered even if luggage is handled roughly.
For chefs and outdoor cooks traveling with multiple knives, the Blade Guard® Waxed Canvas Chef Knife Roll provides organized, protected storage for up to 4 knives in individual pockets — water-resistant waxed canvas, brass hardware, built for the kitchen and the road.
Frequently Asked Questions
Is an ulu knife hard to use?
No — but it requires a different technique than a standard chef's knife. The rocking motion feels unfamiliar at first but becomes natural quickly. Most users find they're comfortable with the technique within a few minutes of practice. The key is letting the blade geometry do the work rather than forcing cuts.
What's the best cutting surface for an ulu knife?
A wooden cutting board or a curved wooden bowl (often sold with ulu sets) works best. The curved bowl matches the blade's arc and is ideal for herb chopping and mincing. Avoid glass or ceramic cutting surfaces, which damage blade edges.
How do I clean an ulu knife?
Hand wash with warm soapy water and dry immediately — do not put in the dishwasher. Dishwasher heat and detergent damage both the blade edge and handle materials. Dry thoroughly before returning to the sheath to prevent moisture buildup against the blade.
How often should I sharpen an ulu knife?
Sharpening frequency depends on use. For regular kitchen use, a light sharpening every few months is typical. Proper storage in a fitted sheath significantly extends the time between sharpenings by preventing edge contact with hard surfaces between uses.
Can I use an ulu knife for outdoor and camping use?
Yes — ulus are excellent outdoor knives for fish cleaning, game processing, and camp cooking. Outdoor-focused makers like Silver Stag produce ulus specifically designed for field use. Always transport with a fitted blade guard and store safely in camp.
