Water Sharpening (best)
1. Remove the clear guide, fill the recess under the ceramic wheel with water and replace guide.
2. Hold sharpener firmly on a flat surface.
3. Align your blade within the guide, slide the blade back and forth through the ceramic wheel 10 - 20 times from heel to tip (applying light pressure) until desired sharpness has been achieved.
4. Rinse and dry your knife thoroughly.
5. Sharpen twice a month (or to suit) to maintain the desired edge sharpness.
Dry Sharpening (quick) - Follow steps 2 - 5, as above.
We recommend that after 12-24 months, depending on the frequency of use, you change the ceramic sharpening wheel in order to maintain your knife’s cutting edge to a high standard.
Replacement wheels are available as a set of two.
Cleaning the hand-held sharpener
The sharpener should be cleaned periodically by hand, lifting the clear guard off to wipe inside using a damp micro-fibre cloth and then dried thoroughly before replacing the guard. The ceramic wheel can be removed and washed in the dishwasher to prevent a build-up of sharpener dust.
Caring for Wooden Knife Storage and Kitchen Accessories:
For a quick clean, simply wipe over with a damp microfibre cloth and thoroughly dry. Or for a comprehensive clean wash with hot, soapy, water and dry thoroughly. Treat with a suitable food-safe mineral oil on a regular basis to maintain optimum condition. Wipe off excess oil and allow to dry before using.
Use a dry microfibre cloth, (dampened for more stubborn marks) and dried immediately after cleaning.
Caring for your Signature Knives:
By hand (recommended):
• Rinse the Signature knives to remove any traces of food.
• Wash gently in warm, soapy, water with a soft cloth. There is no need to soak your Signature knives.
• Thoroughly dry stainless steel knives individually.
• For the best finish, apply a non-abrasive metal polish.
In the dishwasher:
• Ensure your dishwasher setting are set as per the manufacturers' instructions for water hardness in your area.
• Maintain the appropriate salt and rinse aid levels in your dishwasher.
• Before placing in the dishwasher, rinse Signature knives to remove all traces of food.
• Wash stainless steel Signature knives separately to other metals, such as silver, in order to keep them in optimum condition.
• The best detergents for Signature knives are free from chlorides and citrus additives.
• Standard dishwasher programmes are recommended, there is no need to rinse and hold Signature knives.
• Occasional application of mineral oil to the handles of kitchen knives will maintain their colour. Remove any excess oil before use.

Design Story: Signature Knives (2005-2007)
Design Director, Paul deBretton Gordon was first tasked with this project when he joined Robert Welch. He reflects "The design process for the Signature knife range was rooted in questioning all aspects of functionality, durability, methods of manufacture and ease of use." 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.
