Walk into the world of Japanese knives and you hit a wall of unfamiliar names almost immediately: gyuto, santoku, nakiri, bunka, petty, sujihiki, yanagiba, deba, honesuki, usuba, kiritsuke. It sounds like a lot to memorise, and most beginners quietly assume they need half of them. They don't. Once you understand what each shape is actually built to do, the whole catalogue collapses into a handful of decisions, and picking your first knife stops being intimidating.
The trick is to stop thinking about names and start thinking about jobs. Almost every Japanese kitchen knife exists to solve one specific cutting problem well, and grouping them by that job makes the differences obvious.
The all-rounders: gyuto, santoku, bunka
If you only ever own one Japanese knife, it comes from this group. The gyuto is the Japanese take on the Western chef's knife, longer and with a curved belly that lets you rock through onions, herbs and most proteins. The santoku is shorter and flatter, which favours a straight up-and-down chop and feels more controlled in smaller hands or smaller kitchens. The bunka is essentially a santoku with an angled reverse-tanto tip, trading a little sweep for a sharper point that excels at detail work. None of these is objectively better. They are three answers to the same question, which is "what do I reach for ninety percent of the time?"
For vegetables: nakiri and usuba
When you spend a Sunday breaking down a mountain of produce, a dedicated vegetable knife earns its place. The nakiri is a flat, double-bevelled rectangle that drops straight down and pushes through cabbage, carrots and squash with almost no rocking. It is friendly, cheap to enter, and genuinely fun to use. The usuba is its single-bevel professional cousin, the tool behind those paper-thin katsuramuki cucumber sheets you see in Japanese restaurants. The usuba demands practice and proper sharpening, so it is a specialist's choice rather than a first purchase, but it explains where the nakiri's design came from.
If you want the full breakdown of how these shapes relate to one another, we put together a full guide to the types of Japanese knives that lays them out side by side.
Fish and slicing: yanagiba, sujihiki, deba
Long, thin blades exist for one reason, which is to slice cleanly in a single pull without sawing. The yanagiba is the classic single-bevel sashimi knife, drawn through fish in one stroke so the surface stays glassy rather than torn. The sujihiki is its double-bevelled, more versatile relative, at home slicing roast meat and portioning cooked proteins as well as fish. The deba, by contrast, is heavy and thick, built to break down whole fish and take on bones that would chip a thinner blade. These three often get lumped together because they all touch fish, but they cover the full arc from butchery to the final elegant slice.
Precision work: petty, honesuki, kiritsuke
The last group is about control. The petty is a small utility knife for the jobs too fiddly for a big blade: peeling, trimming, segmenting citrus, mincing a single shallot. It is the quiet workhorse most people underrate. The honesuki is a stiff, pointed boning knife designed around poultry, following joints and separating meat from bone with real precision. The kiritsuke sits slightly apart, a hybrid with a dramatic angled tip that combines slicing and general prep, traditionally a mark of a head chef and today a stylish do-most-things option for confident cooks.
Which one first?
Here is the honest answer most guides dance around. Start with one all-rounder, either a gyuto or a santoku, chosen by how you naturally cut. If you rock, buy the gyuto. If you chop, buy the santoku. Add a petty next, because a small knife covers everything the big one is clumsy at, and those two blades will handle the overwhelming majority of home cooking. A nakiri comes third if you cook a lot of vegetables. Everything else on the list, the yanagibas and debas and usubas, is worth buying only when a specific task in your kitchen keeps demanding it.
The catalogue looks endless from the outside, yet the path through it is short. Learn the jobs, buy for the jobs you actually do, and you will spend on the two or three knives that change how you cook instead of a drawer full of shapes you never reach for.
