Best Kitchen Knives 2026: The Hardness Nobody Publishes

The most-reviewed knife set in this ranking and the cheapest per knife: 25,688 ratings at 4.7 stars, 82 per cent five-star and 1 per cent one-star, for £16.19, with six knives, six matching covers and a blade length field that says six inches. It is a coloured set — paring, utility, santoku, chef's, bread and carving, each with a plastic sheath — and it is ranked fifth in Amazon's Kitchen Knife Sets category.

Its most useful line is the first one, because it settles what a piece is. Twelve pieces, it says, including six knives and six covers, which means half the product is packaging that you keep. That is not a criticism of this set specifically; it is how the category counts, and it makes the number on the front of a box nearly useless as a comparison. A 14-piece set two entries down this page is fourteen pieces with a block and a pair of shears; this one is twelve with six sheaths; and a five-piece set further down is five knives and no accessories at all. The only honest way to compare them is by counting blades.

The steel is described as stainless, with no hardness figure and no edge angle, which is true of eight of the ten listings here. What the set has instead is volume and evidence: 671 grams across six knives, plastic handles, a dishwasher warning that says no, reviews that call the blades very sharp and the sizes exactly what was wanted, and a price that works out at £2.70 per knife. For a first kitchen, a rented flat or a house where knives go missing, that arithmetic is the whole argument.

The set that gives its lengths in centimetres, and the only one here that names its edges. It is fourteen pieces for £16.79, ranked first in Amazon's Block Sets category on 21,639 ratings at 4.7 stars with 81 per cent five-star and 2 per cent one-star, and it is the set to buy if you want a block on the worktop rather than six sheaths in a drawer.

Its bullets are the most useful description in this ranking, because they enumerate the pieces with measurements: a 20.3-centimetre chef's knife, a 20.3-centimetre slicing knife, a 20.3-centimetre bread knife, a 14-centimetre utility knife, a 9-centimetre paring knife and so on. That is a blade-by-blade account rather than a single figure, and it makes a real difference when the choice between one set and another is whether it contains a bread knife. The listing also fills the blade edge field with serrated, plain and straight, which is the only time that field is used properly in ten listings and is worth a sentence: a bread knife is serrated, a chef's knife is plain, and knowing which knives in a block are which saves the second half of the block going unused.

Its specification then contradicts that care in the way this site has made familiar. The item length field says 7.87 inches, for a set whose other measurements are in centimetres and whose longest knife is 20.3 centimetres. The block's own dimensions are not given. The steel is high-carbon stainless with no hardness figure, the handles are plastic, and it is not dishwasher safe. Its reviews are about value rather than performance — excellent for the price of such a large set, a nice value starter set for everyday use — and at £16.79 it is the better of the two Amazon Basics options here if you want a block.

The set Amazon ranks first in Kitchen Knife Sets, and at £9.99 the cheapest way here to get five proper knives: 6,455 ratings at 4.6 stars, 76 per cent five-star and 3 per cent one-star. The five are a chef's knife, a filleting knife, a bread knife, a paring knife and a utility knife, colour coded so that a household can keep track of which is which, with non-stick stainless blades and steel handles.

The useful field here is the size, because it gives all five: 4.5 inches, 8 inches, 8 inches, 8 inches and 3.5 inches. Reading that is the only way to understand the set — three of the five knives are eight inches, which is a chef's knife, a bread knife and a carving knife, and the other two are small. It is also the only field in this ranking that expresses a set's contents as a list rather than as one figure for everything, and it is in inches on a page where the blade lengths are otherwise unstated.

Two of its fields are nonsense, in the pattern this site keeps finding. The item length is recorded as 2 centimetres, which would make the set a thumbnail; the model number is 99922 and the manufacturer part number is 00023, two unrelated strings for one product. The steel is described only as stainless, with no hardness figure. What the price buys is colour coding and non-stick coating, both of which matter in a shared kitchen: the coating makes cleaning easier and the colours make it obvious whose knife is whose, which at £9.99 for five is the trade against two or three better blades.

The first single knife here that names its steel, and the one whose sharpness claim runs away from it. The blade is 10Cr15CoMoV — a Japanese high-carbon stainless grade, equivalent to the same family the SHAN ZU knives further down this page use — and the listing says it provides twice the sharpness, without saying twice what. That is the standard failure of the category: a comparative with no baseline, in the place where the hardness figure should be. The hardness is what a buyer can check and compare; twice the sharpness is a sentence nobody can test.

Its second problem is where Amazon has filed it. This is an eight-inch chef's knife, and it ranks first in the Santoku Knives category, while the SHAN ZU santoku at number eight ranks first among Boning Knives. Neither is a filing a buyer would choose, and it is a reminder that the category badges are algorithmic rather than editorial — the same product can hold a number one badge in a category it does not belong to.

The knife itself is a serious object for £31.44: a full-tang 8-inch blade with a wooden handle, a matte finish, 2,471 ratings at 4.6 stars with 81 per cent five-star and 3 per cent one-star, and the model number field filled with the words 8 inch Chef Knife rather than a code. Its reviews are about balance and edge: well balanced with a sharp blade that cuts with ease, and good quality for the price with a blade surprisingly sharp out of the box. If you want one knife rather than a set, this is the second-best-regarded single blade here after the SHAN ZU santoku, and it is the one with the most buyers.

The knife that solves the problem this ranking is about, by avoiding it. Nine of the ten listings here decline to publish a steel hardness or an edge angle, which leaves a buyer unable to compare one blade with another on the only two measurements that predict how long it will stay sharp. This one does something better than publishing the number: the sheath contains a sharpener, so every time the knife is drawn out and put back it is honed along a fixed angle. The item type field says exactly that — All Purpose Small Kitchen Knife with EdgeKeeper Knife Sharpener Sheath — which is one of the few specification fields on this site that tells you what the product does.

The knife itself is small: an 11.5-centimetre blade in high-carbon stainless steel, 78 grams, with a stainless handle, sold as an all-purpose utility knife for £7.19. Its record is 907 ratings at 4.6 stars with 74 per cent five-star and 1 per cent one-star, which makes it the third-best distributed product here, and the reviews are short and pleased — a brilliant little knife, very sharp, used almost every day, and one buyer who finds it slices through steak like soft butter.

The trade is the geometry. A self-sharpening sheath hones at one angle and cannot re-profile an edge, so the knife will stay as sharp as its factory grind rather than becoming sharper, and the blade is short by design because a long knife does not fit the mechanism. What it buys for £7.19 is a knife that will still be usable in five years in a house where nobody owns a whetstone — which is most houses. Its item length field, meanwhile, says 4.5 inches for a knife whose blade is given in centimetres, the usual unit confusion in miniature.

The first of two SHAN ZU knives here, and one of only two listings in the ranking that publishes a hardness figure: 63 HRC, in the bullets, for a blade of Japanese high-carbon powder steel with an oak handle. That is the number that separates one knife from another in any meaningful way, and the fact that it appears twice in ten listings is the finding of this article. Its sibling at number eight states 62 HRC for a different knife in the same brand, so the two are consistent with each other and inconsistent with the eight listings that say nothing.

Its own page has the flaw this site has taught you to expect. The title says 18 centimetres, and the blade length field says 20. Two centimetres is a real difference in a knife — it is the difference between a santoku and a small chef's knife — and the two figures sit on the same page with no way to tell which is right. The blade material is recorded twice, once as high carbon steel and once as Japanese 10Cr15MoV steel, which at least agree with each other, and the item type is a santoku knife which then ranks first in Boning Knives, a category this knife does not belong to.

What £23.99 buys is a three-layer or laminated powder-steel blade with a hardness in the low sixties, which is the range where a knife takes a keen edge and holds it without becoming brittle. The reviews are about sharpness and finish: very sharp and beautiful looking, with one buyer noting that only time will tell whether it lasts, and another saying it covers everything they were looking for. It is the knife to buy if you want a santoku with a stated hardness and you are willing to check the photograph to see which length it really is.

The only product in this ranking whose country of origin is not China: the specification says Switzerland, which for Victorinox is not a claim but a fact, and it is the single most distinctive line in the comparison. Everything else here is made in China — the Amazon Basics sets, the nuovva set, both SHAN ZU knives, the HOSHANHO and the Smithfield — and origin is a fair proxy for what you are buying in a category where almost nobody publishes the steel.

The set is four paring and vegetable knives between 8 and 11 centimetres, which is a specific purpose rather than a general one: these are the knives for tomatoes, fruit, small vegetables and the jobs that a large chef's knife does badly. The blade length is given in millimetres, 110 of them, the handle is polypropylene, the whole set weighs 107 grams, and they are dishwasher safe where the Amazon Basics sets are not. Its record is 484 ratings at 4.7 stars with 83 per cent five-star and no one-star reviews at all, the cleanest distribution in the ranking.

The honest note comes from its own reviews, and it is about the handles: one buyer calls the knives sharp and strong but describes the handles as not very robust and says they will be interested to see whether they last. That is the trade with lightweight polypropylene handles at this price, and it is worth knowing before buying four knives for £17.62 on the strength of the brand. If you want a set for fine work and you care where it was made, this is the one; if you need a chef's knife, look at the two SHAN ZU listings above and below it.

The only product in this ranking that publishes both of the numbers that decide what a knife is worth: a steel hardness of 62 HRC and an edge ground to 12 degrees. Everything else here gives one, or a word — a sharper blade, a harder blade, twice the sharpness — or nothing at all, and this listing puts the two figures that can be compared into the same sentence, on a knife that costs £19.05.

It is also the best-rated knife here at any sample size: 418 ratings at 4.8 stars with 85 per cent five-star and 1 per cent one-star, which is the strongest distribution in the ranking. The blade is an 18-centimetre santoku in 10Cr15MoV steel — the same family as the HOSHANHO and the other SHAN ZU above it — with a five-layer laminated structure against rust and chipping, a Pakkawood handle weighing 209 grams all in, and a total length of 31.2 centimetres.

The twelve-degree edge is the part worth understanding, because it explains the hardness and the price. A shallow angle like that cuts more cleanly than the twenty degrees of a German chef's knife and is correspondingly more fragile, which is why the steel has to be hard: at 62 HRC, the steel resists rolling over at the thin edge where a softer blade would fold. That combination is what a Japanese knife is, and it comes with an obligation — no dishwasher, no bones, no frozen food, hand-washed and dried. Its reviews are about the edge and the finish: excellent quality and feel, sharpens well, superb and very sharp, easy to use and highly recommended. Its category badge says second in Fruit and Vegetable Knives, which is at least closer to the truth than the badges on its stablemate.

The set that shows the failure in one phrase. One of its bullets is Sharpen to Perfection, in capitals, and that is the entirety of what the listing says about the edge: no hardness, no angle, no steel grade beyond stainless. It is the same emptiness as the harder, stronger blade on the Richardson Sheffield knife below and the twice the sharpness on the HOSHANHO above, and together those three listings are the reason this article exists: on a page of ten kitchen knives, two publishers manage a hardness figure and one manages an angle, and the rest substitute adjectives.

What the set actually is, is reasonable for £9.70: three knives — a chef's knife, a utility knife and a parer — with a non-stick coating on stainless blades, stainless handles, a stated blade length of 15 centimetres and an item length of 29.5 centimetres, weighing 230 grams, dishwasher safe. The non-stick coating is worth a moment because it is genuinely useful in a cheap knife: it reduces friction on sticky vegetables and it means the blade cleans with a rinse, at the cost of a surface that will wear and cannot be sharpened as finely as bare steel.

Its record is 197 ratings at 4.4 stars, 72 per cent five-star and 5 per cent one-star, and its reviews contain the most honest sentence in this ranking: very sharp knives, time will tell if they last. That is exactly the uncertainty a missing hardness figure creates, and it is not the buyer's fault. Its model number is recorded as Knives101, which is a description rather than an identifier, and at £9.70 for three coated blades it is a fair kitchen starter rather than a knife anyone will keep.
