Why Every Kitchen Needs a Japanese Chef Knife

Updated September 2026 · 7 min read · UK Japanese-steel knife specialists

Most kitchens run on one knife. It does the onions, the chicken, the herbs and the squash, and it is the only blade that ever really leaves the block. So the question is not whether you need a chef's knife — you already have one — but whether swapping it for a Japanese-steel one is worth the money.

We think it is, and we will tell you exactly why rather than asking you to take our word for it. Below: what actually changes when you move to a Japanese-steel blade, which two we would put in a first-time buyer's hand, and the honest trade-offs. If you would rather skip the reading, our live Japanese chef knives are all in one place.

The short answer

A Japanese-steel chef knife is not a different tool. It is the same tool, built to a tighter specification. The core steel is harder, so the maker can grind the blade thinner and put a narrower edge on it without that edge folding over the first time it meets a carrot. Thinner blade plus narrower edge means the knife parts food rather than wedging it apart, and because there is less steel in the blade, it weighs less in your hand.

What you give up is forgiveness. A harder edge chips if you use it on bone, frozen food or a glass board, and it does not enjoy a dishwasher. If you are happy to hand-wash and dry a knife, that is the entire cost.

What actually makes a Japanese chef knife different

Harder steel

The core of the blade is a high-carbon stainless steel: VG10 or AUS-10, depending on the range. Both are stainless, so they are not the temperamental plain carbon steels people sometimes picture — but both are meaningfully harder than the softer stainless used in a typical European kitchen knife. Hardness is the thing that makes everything else on this list possible. If you want the detail, we wrote a plain-English guide to the best steel for kitchen knives.

A thinner, keener edge

A European chef's knife is usually ground to around 20 degrees per side. A Japanese-steel knife like ours is taken to roughly 15 degrees per side. That five-degree difference sounds trivial and is not: a narrower angle means less steel meeting the food, so the blade slips through a tomato skin or an onion layer instead of pushing it. Only harder steel can hold that angle without the edge rolling, which is why you cannot simply sharpen a soft European blade to 15 degrees and get the same knife. More on this in our guide to the correct Japanese knife sharpening angle.

Less weight

A thinner blade is a lighter blade, and a lighter knife is a more controllable one. A heavy European knife does some of the work for you by falling through the food; a lighter Japanese-steel knife asks you to steer it instead, which is why cooks who do a lot of fine prep tend to prefer one. After an hour of prep your wrist notices the difference too.

Better edge retention

Harder steel wears down more slowly, so the edge you get out of the box lasts longer before it needs a stone. This is the benefit people underestimate: it is not that the knife is sharp on day one, it is that it is still sharp in month four.

Cleaner cuts

A keener edge severs rather than crushes. In practice that means basil and other soft herbs bruise and blacken less, tomatoes and peppers keep their shape instead of collapsing, and cut faces on meat and fish look tidy rather than ragged. That is the part you can actually see on the board.

Two Japanese chef knives we would start you on

Both of these are double-bevelled, high-carbon stainless, currently in our range, and rated by real customers. Prices are in GBP and correct at the time of writing.

What can you use a Japanese chef knife for?

Almost everything. A chef knife is the general-purpose blade: slicing fish fillets, jointing and dicing chicken, chopping onions, breaking down cabbages and squash, shredding herbs, portioning cooked meat. The jobs it is not for are the heavy ones — bones, frozen food, hard-shelled squash you would normally attack with a cleaver — because a thin, hard edge chips where a thick soft one would just dent.

Chef knife or santoku?

This is the question most people are really asking. A gyuto is the Japanese version of a Western chef's knife: longer, pointed tip, curved belly, good at rocking cuts and big jobs. A santoku is shorter and flatter with a rounded tip, which suits a straight up-and-down chop and a smaller board. If you already cook with a chef's knife and want a single do-everything blade, an 8 inch gyuto is the direct upgrade. If you have a small kitchen and mostly chop vegetables, a santoku will feel better.

We have gone through both comparisons properly: our santoku vs chef knife comparison covers the shape and technique differences, and the gyuto vs chef's knife guide explains why a gyuto and a chef's knife are the same category with two names. If you are still mapping the wider range, our overview of the types of Japanese kitchen knives is the place to start.

Is it harder to look after?

A little, and it is a short list. Hand-wash and dry the blade straight after use rather than leaving it in the sink; keep it away from bone, frozen food and glass or stone boards; store it on a magnetic rack, in a block or in its scabbard rather than loose in a drawer; and when it does dull, use a whetstone rather than a pull-through sharpener, which grinds a coarse European angle back onto a knife that does not want one.

Storage is the one people get wrong most often — a blade knocking against other cutlery in a drawer will lose its edge faster than any amount of chopping. We cover the options in how to store a Japanese-steel knife.

Frequently asked questions

What makes a Japanese chef knife different from a European one?

Three things: the steel, the edge and the weight. Japanese-steel knives use a harder high-carbon stainless core such as VG10 or AUS-10, which lets the blade be ground thinner and taken to roughly 15 degrees per side instead of the 20 degrees typical of a European knife. The result is a keener, finer blade that is also noticeably lighter in the hand.

Gyuto or santoku - which Japanese chef knife should I buy?

A gyuto is the Japanese take on a Western chef's knife: longer, with a pointed tip and a curved belly that suits rocking cuts and bigger jobs. A santoku is shorter and flatter with a rounded tip, which suits a straight up-and-down chopping motion and smaller boards. If you want one do-everything knife and you already cook with a chef's knife, start with an 8 inch gyuto.

Is a Japanese chef knife worth the money?

If you cook most days, yes. Around the 90 to 100 pound mark you are buying a harder steel core, a thinner grind and a much finer factory edge, and it holds that edge longer between sharpenings. If you cook rarely, or you want a knife you can be rough with and put through the dishwasher, a cheaper European knife is the more sensible buy.

Are Japanese-steel knives harder to look after?

They ask for a little more respect rather than a lot more work. Hand-wash and dry the blade straight after use instead of leaving it wet or putting it in the dishwasher, keep it off bones and frozen food, store it on a magnetic rack or in a block, and sharpen it on a whetstone rather than a pull-through sharpener. That is the whole routine.

Can a beginner use a Japanese chef knife?

Yes. Every chef knife we sell is double-bevelled, which means it is ground on both sides and cuts the same way a European knife does, so there is nothing new to learn about technique. The only adjustments are that the edge is sharper than you may be used to, so slow down for the first few sessions, and that it prefers a wooden or plastic board to glass or stone.

Are Japanese chef knives made of carbon steel?

The ones we sell are not plain carbon steel. They are high-carbon stainless steels, VG10 and AUS-10, which give you the hardness and edge retention people associate with carbon steel without the same tendency to rust and stain. They will still mark if you leave them wet, so dry the blade after washing.

The bottom line

If you cook most days, a Japanese-steel chef knife is one of the few kitchen upgrades you notice immediately and keep noticing. Harder steel, a keener edge at roughly 15 degrees per side, and less weight add up to a knife that does the same job with less effort and stays that way for longer. The trade is a bit of care, and for most cooks that is a trade worth making.
