The picks in depth
Victorinox Fibrox Pro Chef's Knife, 20cm (5.2063.20)
Why it won
The knife most home cooks should buy: professional-grade, near-indestructible and a fraction of premium prices.
High-carbon stainless blade holds a good working edge and is easy to re-sharpen
Officially dishwasher-safe and famously abuse-tolerant — no babying required
Cheapest pick here yet a genuine professional standby, backed by a lifetime warranty
Trade-off: Stamped and lighter than forged rivals, so it lacks the premium heft some cooks want
Robert Welch Signature Cook's Knife, 20cm
Why we recommend it
The value sweet-spot above budget: a forged, full-tang lifetime knife that feels 'proper' without premium pricing.
Fully forged full tang with better in-hand balance than the stamped Victorinox
Multi-award-winning design with a 15-degree hand-finished edge and a lifetime guarantee
Curved belly suits a rocking chop and the tougher ~56 HRC steel re-sharpens easily
Trade-off: Roughly double the Victorinox price for the same everyday cuts
Global G-2 Cook's Knife, 20cm
Why we recommend it
The agile, keen-edged pick for cooks who find German knives tiring and want precision over power.
Lightweight and nimble — reviewers rate it for agility and reduced fatigue over long prep
Keen thin 15-degree edge from Cromova 18 steel; a frequent test winner for sharpness
Seamless one-piece build with no crevices and a distinctive balanced dimpled handle
Trade-off: All-steel dimpled handle is polarising and can feel cold or slippery to some
Wusthof Classic Cook's Knife, 20cm
Why we recommend it
The heavy, forged 'buy once' Western knife for cooks who want power and heft through dense produce.
Heaviest, most robust build here — best for power tasks and a rocking chop
Forged full bolster adds heft and knuckle protection, plus a lifetime guarantee
Long-standing benchmark German brand stocked by mainstream UK retailers
Trade-off: Heft can tire cooks who prefer Japanese agility
Kai Shun Classic Chef's Knife, 20cm
Why we recommend it
The keenest, most special knife here — for confident cooks happy to maintain a hard, thin edge.
Hardest edge here (~61 HRC) so it stays keenest longest
Steeply tapered thin blade is sharper than typical Western knives, yet lighter than European chef's knives
Showpiece 32-layer Damascus finish and pakkawood handle, with a 10-year warranty
Trade-off: Most expensive pick and the most demanding to maintain — hand-wash only, no soaking

Frequently asked questions
What is the best kitchen knife to buy in the UK?
For most people it's the Victorinox Fibrox Pro 20cm chef's knife. It's a professional-kitchen staple that holds a good edge, stays comfortable over long prep, is officially dishwasher-safe and near-indestructible — yet costs a fraction of premium Japanese or German knives. Spend more only if you specifically want a forged, weightier knife (Robert Welch or Wusthof) or the keenest Japanese edge (Global or Shun).
German vs Japanese chef's knives: which is better?
German knives (Victorinox, Robert Welch, Wusthof) use softer, tougher steel around 55-58 HRC — forgiving, easy to re-sharpen and better for heavy tasks and a rocking chop, though they need more frequent honing. Japanese knives (Global, Shun) use harder steel at around 56-61 HRC that holds a keener edge far longer and tends to be lighter and more precise, but is more brittle, more chip-prone and usually hand-wash only. Pick German for power and low fuss, Japanese for sharpness and agility.
How much should you spend on a good chef's knife?
Indicatively, a genuinely good 20cm chef's knife starts at around £28-£43 for the Victorinox Fibrox, rising to about £68 for the forged Robert Welch, roughly £139-£140 for the Global G-2 or Wusthof Classic, and around £195 for the premium Kai Shun. You don't need to spend big — the Victorinox performs the same everyday cuts as knives several times the price — but paying more buys forged construction, a keener edge or a showpiece finish. Prices are indicative and fluctuate, so check the retailer before buying.
Do I need a knife set or just a chef's knife?
For most home cooks a single 20cm chef's knife does around 80% of prep, so it's the one blade worth investing in first. A paring knife and a serrated bread knife cover almost everything else, and buying those three individually usually beats a large block set full of knives you'll rarely use. Start with the chef's knife here, then add a couple of specialists rather than a whole set.
