About the Robert Welch Signature cook's knife
Robert Welch is a British design studio founded in 1955 in Chipping Campden in the Cotswolds. The founder was a pioneer of British stainless steel design, and his work sits in the permanent collections of the V&A and the MoMA. The company, still family-run, has produced the Signature kitchen knife range since 2009 in collaboration with professional chefs.
The Signature Cook's Knife is the flagship of the Signature range. It's fully forged from a single piece of German 1.4116 high-carbon stainless steel, which means the blade, bolster and tang are one continuous piece for better balance and strength. Each knife is finished with a hand-applied 15-degree Japanese-style blade edge, which sits closer to a Japanese chef's knife angle than a traditional German 20-degree edge. The handle is ergonomically shaped POM plastic with the Robert Welch insignia inset in steel.
Choose your size
The Signature Cook's Knife comes in five sizes. Each shares the same construction but suits a different hand size, cutting style and volume of food preparation.
12cm Cook's Knife - around £50
The smallest cook's knife in the range. Suits anyone with smaller hands, limited counter space, or a preference for close-control cutting. A solid all-rounder for everyday prep, though undersized for large roasts, melons or butchery work.
14cm Cook's Knife - around £55
A step up in reach without losing control. Popular with home cooks who want one general-purpose knife rather than a roll of specialists.
16cm Cook's Knife - around £70
A middle-ground size that splits the difference between the small 14cm and the full 18cm chef's knife. A good compromise for anyone unsure between home-cook and professional sizing.
18cm Cook's Knife - around £85 (our default pick)
Robert Welch's own reference cook's knife. Included in their three-piece Home Chef Set. This is the size most professional chefs reach for, and it's the size we'd recommend as the default gift choice.
20cm Cook's Knife - around £90
The largest in the range. Suits confident cooks handling bigger roasts, melons and whole chickens regularly.

Who it's suitable for

It's a common gift for new homeowners, enthusiastic home cooks, and people transitioning from cheap supermarket knife sets to something they'll keep for decades. The 25-year guarantee and full-tang construction make it a genuinely buy-it-for-life piece rather than something to replace in five years. Age verification may be required at Amazon UK delivery, since it's a kitchen knife.
Frequently asked questions
Where are Robert Welch knives made?
Robert Welch knives are designed in Chipping Campden, Gloucestershire, at the company's Old Silk Mill studio. The Signature range blades are manufactured in Germany using 1.4116 stainless steel and finished to Robert Welch specifications.
Which size Robert Welch cook's knife should I buy?
For most home cooks, the 18cm Cook's Knife is the default recommendation. It's the size professional chefs most commonly use and the one Robert Welch includes in their own Home Chef Set. Choose the 14cm for smaller hands or limited counter space, or the 20cm if you regularly work with large roasts and whole vegetables.
Is the Robert Welch Signature knife dishwasher safe?
Yes, the Signature range is rated dishwasher safe by Robert Welch. However, hand-washing is recommended to preserve the 15-degree blade edge. Dishwasher cycles dull blades faster and can chip edges against other cutlery.
How long is the Robert Welch warranty?
Robert Welch offers a 25-year guarantee on the Signature kitchen knife range, covering manufacturing defects. Accidental damage is not covered.
How much does a Robert Welch cook's knife cost in the UK?
UK pricing starts at around £50 for the 12cm Cook's and rises to around £90 for the 20cm. The flagship 18cm Cook's typically sits around £85 on Amazon UK. Prices vary, so check the current listing.
What is the difference between the Robert Welch Signature and Professional ranges?
The Signature range is Robert Welch's design-led consumer collection, aimed at home cooks and developed in consultation with professional chefs. The Professional range is a separate collection built specifically for commercial kitchens, with different handle shapes and a tougher construction. For home kitchens, the Signature range is the standard recommendation.
