Design Notes

Designed in consultation with professional chefs, the award winning Signature 18cm/7.5" cook's knife is an all-purpose kitchen knife with a curved blade for chopping and rocking cutting actions.

Our chef’s and cook’s knives now have an added edge, having been recognised as a Which? Best Buy.

Cook’s knives are a multi-purpose kitchen tool, and a great starter knife if you are only intending to buy one. Their curved blades allow for a two step chop and rock action, ideal for meat (raw or cooked) and hard vegetables as well as herbs, nuts and salads and for crushing garlic into a paste. 

The Japanese-style blade edge is at a 15° angle and the knife has an ergonomically shaped handle for comfort, balance and to minimise fatigue in use. 

Also available: cook's knife 12cm, cook's knife 14cm, cook's knife 16cm, cook's knife 20cm, cook's knife 25cm 

Choosing the right kitchen knife, the best knife for the task at hand, makes preparing a meal easier. Selecting the perfect knife for slicing, dicing or chopping allows you to work with accuracy and cut consistently, which helps food to cook more evenly. The specially hardened, high-quality, German stainless steel used for our Signature knives is durable, easy to clean and maintain.

When washing your kitchen knives by hand (recommended):
Rinse your kitchen knives to remove all traces of food as soon as possible after use. Wash in warm soapy water with a microfibre cloth or non abrasive brush**. Try to avoid soaking your kitchen knives and always dry thoroughly immediately after washing, using a microfibre cloth.

When washing your kitchen knives in a dishwasher:
• Wash on a short hot cycle 65°-75°C (150°-167°F)
• Use quality branded all in one dishwasher tablets*
• Keep Rinse Aid topped up and Salt (for hard water areas).
• Avoid washing with non-stainless steel metals (this can cause rust staining).
• Ensure the dishwasher filters are cleaned and use a proprietary dishwasher cleaner regularly.

*For UK customers we recommend Fairy Platinum Plus and for US customers Cascade Platinum Plus

**Always avoid scouring with pads or abrasive cleaners as this will scratch the surface.

Additional care of knife handles:
Periodically apply a mineral oil to handles to maintain their colour. Please remove any excess oil.

He worked in collaboration with Rupert Welch to perfect the knives using the experience of professional chefs. The knife range was rigorously tested over three years. Signature knives are now much loved by both professional and amateur chefs alike.
