The ulu knife, and when it beats a chef's knife

Updated 12 August 2026 · VegEco editorial desk

An ulu is a crescent blade with the handle mounted above its centre, so you cut by rocking straight down with your forearm rather than slicing forward from the wrist. Traditionally an Inuit, Yup'ik and Iñupiaq tool, it is sold today as a set with a hardwood or stone bowl that matches the blade curve. In a plant-forward kitchen it earns its place on herbs, leafy greens, nuts and dense root vegetables — and it is genuinely worse than a chef's knife at several other jobs.

What to look for

Respect the origin: The ulu is a living Indigenous tool, not a novelty. Buying from Alaska Native artisans or cooperatives keeps the money with the communities the design comes from; look for a named maker rather than an unattributed import.
Blade steel decides the maintenance: High-carbon steel takes a keener edge and touches up easily but will rust if left wet. Stainless holds up to neglect and dishwasher-adjacent kitchens at the cost of edge retention. Choose for your habits, not the photo.
Handle material and grip height: Hardwood, antler and horn are traditional; wood is the practical vegan choice and the easiest to grip wet. Check there is enough clearance between handle and blade for your knuckles.
The bowl is not optional for chopping: A matched concave bowl is what makes the rocking motion efficient — herbs and nuts stay in the cut zone instead of scattering. Without it, an ulu on a flat board underperforms a chef's knife.
Sharpening is a different geometry: The curved edge needs a rod, small stone or a curve-friendly sharpener drawn along the arc. Pull-through V sharpeners built for straight blades will ruin the profile.
Storage and safety: The exposed arc is a hand hazard in a drawer. Buy or make a sheath, or store it blade-down in the bowl. Cut with the flat of your other hand on the handle top, fingers well clear of the arc.

What the ulu does well, and what it does not

What the ulu does well, and what it does not
Option	Best for	Why it works	Watch out
Herbs and leafy greens	Fast, even mincing	The rocking arc in a bowl minces parsley, coriander, kale and cabbage faster than a straight blade with less bruising.	Wet greens clump — dry them first or the blade drags.
Nuts, dates and dried fruit	Contained chopping	The bowl stops the scatter that makes nut chopping tedious on a board.	Sticky fruit needs an occasional blade wipe.
Onions, garlic and ginger	Quick aromatics	Downward pressure through a dense arc handles fibrous ginger and garlic cleanly.	Uniform onion dice is still easier with a chef's knife.
Squash, sweet potato and other dense roots	Leverage cuts	Forearm force straight down beats wrist force through a long blade on hard vegetables.	Halve large squash with a heavy chef's knife first — the ulu is for the sections.
Pizza, flatbread and pastry	One-pass cutting	The arc cuts a full line without dragging toppings, which is why many sets are sold as pizza cutters.	Wooden bowls stain from tomato and oil; wash and dry promptly.
Filleting, peeling, precision slicing	Not the ulu's job	No tip and a fixed arc make fine, thin and detail work awkward.	Keep a paring knife — an ulu set is an addition, not a replacement.

Frequently asked questions

What is an ulu knife used for?

Rocking, downward chopping: herbs, greens, nuts, aromatics, dense root vegetables, and cutting pizza or flatbread. It has no tip, so it is poor at piercing, peeling and precision slicing.

Is an ulu better than a chef's knife?

Only for specific tasks. It minces herbs and chops nuts in a bowl faster and with less effort, but a chef's knife remains more versatile for slicing, dicing and any cut needing a tip.

How do you sharpen an ulu?

Draw the curved edge along a sharpening rod or a small whetstone, following the arc and keeping a consistent angle, then strop or hone lightly. Never use a straight pull-through sharpener.

Do you need the bowl that comes with an ulu set?

For chopping, effectively yes — the concave bowl matches the blade arc and keeps food in the cut zone. For pizza or single straight cuts, the blade alone is fine.

Are ulu handles vegan?

Wooden-handled ulus are; many traditional and premium sets use antler, bone or horn. Check the handle material before buying if that matters to you, and prefer hardwood from a named Alaska Native maker.
