How Much Should You Spend on a Kitchen Knife?

Updated August 2026 · 9 min read · UK Japanese-steel knife specialists

Kitchen knives run from four pounds in a supermarket to four hundred in a specialist shop, and almost nobody explains what actually changes as the number goes up. So you're left guessing whether £90 is sensible or ridiculous.

We sell knives, so treat this with the scepticism it deserves — but the honest answer is that the useful range is narrower than the price range suggests, and there is a fairly clear point at which paying more stops improving how the knife cuts.

What each price bracket actually buys you

Under £30 — you are buying a handle

At this price the steel is soft, low-carbon stainless. It will feel sharp in the shop because it has been ground thin, and it will stop feeling sharp within a fortnight of real use. You can sharpen it, but soft steel gives the edge straight back.

There is one honest use for a knife this cheap: a spare you don't mind lending, taking camping, or leaving in a holiday let. As your main knife it is a false economy — you'll replace it twice in the time a better knife would still be going.

£30–£50 — the first sensible tier

This is where hardened steel starts appearing. You'll find genuine VG10 and AUS-10 cores, proper heat treatment and handles that are fitted rather than glued on. Fit and finish is plainer, the Damascus cladding (if any) is thinner, and the balance is less refined — but the knife cuts properly and stays cutting.

£50–£100 — the sweet spot

Almost everything that matters to how a knife performs is present by £100: a hard steel core, a thin, well-ground edge, a tang that anchors the blade properly, and a handle shaped rather than merely attached. This is the band we point most people towards, and it's where our own best-selling single knives sit.

The difference between a £70 knife and a £100 knife is usually handle material and finishing rather than cutting ability. Both will hold an edge for weeks of home use.

£100–£200 — diminishing, but not zero, returns

Above £100 you're buying refinement: better-figured handle materials, more Damascus layers, tighter grinding tolerances, sometimes a slightly harder core. These are real improvements and a keen cook will notice them. They are not the difference between a knife that works and one that doesn't.

Over £200 — craft, not performance

This is the territory of hand-finished blades, rare handle woods and single-maker output. If you love knives, that's a perfectly good reason to buy one. But be clear that you're buying an object you enjoy owning, not a meaningfully better tool for chopping onions.

Where the money stops working

Three things drive almost all of a knife's real-world performance: how hard the steel is, how thin and well-ground the edge is, and how securely the blade is anchored into the handle. All three are typically maxed out by around £100 in our range.

Everything above that is finish — more Damascus layers, better handle material, tighter tolerances. Lovely, but it doesn't cut a carrot faster. If you're weighing £160 on one knife against £100 on the knife plus £60 on a whetstone, take the second option. A well-maintained mid-priced knife beats a neglected expensive one, every single time. Our guide to sharpening a knife on a whetstone covers how.

What people regret buying

The 15-piece block set. You'll use three of them. The rest is filler that inflates the piece count and eats your budget. If you want a set, buy a small one with knives you'll actually reach for.

Steak knives before a decent chef's knife. Sort out the knife that does 90% of your prep first.

An expensive knife with no way to sharpen it. A knife is a consumable edge on a permanent handle. Budget for maintenance from day one — either a whetstone or a diamond sharpening steel at £49.99.

Buying on Damascus pattern alone. The wavy layering is cladding around the cutting core. It looks superb and adds a little corrosion resistance, but the core steel is what determines how the knife cuts — see Damascus vs stainless steel.

One more thing about the steel

A quick clarification, because it affects how you read prices elsewhere. Our knives use Japanese steels — VG10 and AUS-10 cores hardened to hold a fine edge. That is a description of the steel, not the country of manufacture. Plenty of retailers blur that line to justify a premium; the thing worth paying for is the steel specification and the heat treatment, and you should ask about both before spending heavily.

Frequently asked questions

How much should you spend on a kitchen knife?

For a main kitchen knife you will use most days, budget £70 to £100. That is the band where you reliably get a hardened Japanese steel core, a full or properly anchored tang and a handle that survives years of washing up. Below £30 you are usually paying for a blade that will not hold an edge; above £150 you are paying for finish and rarity rather than cutting performance.

Is a £100 kitchen knife worth it?

Yes, if it is the knife you reach for daily. At around £100 you are buying edge retention, which is the difference between sharpening every few weeks and sharpening every few days. Spread over the years a good knife lasts, the cost per use is very low. It is not worth it for a knife you will use twice a year.

What is the cheapest knife worth buying?

Around the £50 mark. Below that, the compromises are in the steel itself, and no amount of sharpening fixes soft steel. Our entry point is the Riku Damascus VG10 Knife at £49.99, which uses the same VG10 core as knives costing twice as much.

Is it cheaper to buy a knife set or single knives?

Per knife, a set is almost always cheaper. But most people only genuinely use three of the knives in a set. If you are starting from nothing, a set is good value; if you already own working knives, buying two good singles usually beats replacing everything.

Does a more expensive knife stay sharp longer?

Usually, up to a point. Higher-priced knives tend to use harder steel, and harder steel holds an edge longer. Past roughly £150 the steel is often no harder and you are paying for handle materials, Damascus cladding and finishing rather than edge life.

How many kitchen knives do I actually need?

Three. A chef's knife or santoku for most work, a small paring or petty knife for detail, and a serrated bread knife. Everything else is a convenience rather than a necessity.

Should I spend money on a whetstone instead of a better knife?

If your current knife is decent but dull, yes. A £59.99 whetstone will transform a mid-priced knife far more than another £50 on the knife itself. A sharp £70 knife outperforms a blunt £150 one every time.

Why are Japanese-steel knives more expensive?

They use higher-carbon steels such as VG10 and AUS-10 hardened to a higher Rockwell rating, which costs more to produce and to grind. That hardness is what lets the blade take a thinner, longer-lasting edge. Note that this refers to the steel type, not the country of manufacture.
