Serrated Knife Care: 7 Rules for Professional Kitchens
Look after a serrated knife properly and it will cut like new for years. In a professional kitchen a knife is used dozens of times every shift; small habits such as washing, storage and the cutting surface decide how long it lasts.

The seven rules below are widely accepted care practices for serrated knives. Always follow your knife’s instructions first.
1. Wash it right after use
Butter, sugar and dough left between the teeth are harder to clean once they dry. After use, wash the knife with warm water and a soft sponge, with the edge facing away from you.
2. It is dishwasher safe
The GLANZ Croissant & Bread Knife can be washed in the dishwasher. Place it so it does not knock against other utensils, and take it out and dry it as soon as the programme ends.
3. Dry it straight away
Stainless steel resists moisture, but leaving the knife wet can still cause spotting. Dry it with a clean cloth right after washing.
4. Use the right cutting surface
Glass, marble, granite and metal surfaces dull the edge quickly. Use wooden or food-safe plastic cutting boards.
5. Store it separately
In a drawer with other utensils, the teeth get damaged and there is a risk of accidental cuts. Keep the knife in a knife block, on a magnetic strip or in a protective sheath.
6. Leave sharpening to a specialist
Serrated knives stay sharp much longer than straight-edged ones. When sharpening is needed, don’t use a flat whetstone; the serration needs a suitable tapered sharpening rod or a professional sharpening service.
7. Follow a hygiene routine
In professional kitchens, keeping a dedicated knife and board for baked goods is the easiest way to prevent cross-contamination. If you use colour-coded boards, stick to the colour assigned to bread and baked goods.
Frequently asked questions
Because only the tips of the teeth touch the product while cutting, serrated knives stay sharp for a long time. When cutting gets harder and you start pressing down on the product, it is time to sharpen.
