KAI grinding stone 400/1000
No VAT is charged. Shipping costs are calculated at checkout
The KAI whetstone 400/1000 is the ideal tool for both professional and hobby chefs who want to achieve a sharp and precise sharpening of their knives. With a coarseness of 400 grit, it is perfect for repairing and shaping sharpening edges, while 1000 grit provides a finer finish that ensures a sharp and durable edge. This whetstone is designed to be user-friendly and effective, allowing anyone to achieve professional results at home. Whether you work with Japanese or Western knives, the KAI whetstone will help you keep your knives in top shape.
- Combination of 400/1000 grit for versatile sanding
- Ideal for both repairing and honing knives
- User-friendly and efficient design
- Suitable for both Japanese and Western knives
- Ensures a sharp and durable cutting edge
Genuine Japanese kitchen knives are made from various types of hard, high-quality steel and represent the finest in Japanese knife craftsmanship.
To maintain the sharpness of the knife and ensure a long service life, it is important to adhere to the following guidelines:
- Never wash the knives in a dishwasher. Instead, clean the knife by hand with lukewarm water and dry it thoroughly immediately – never let it air dry.
- The knives must not be used for hard items such as frozen foods, bones, cartilage, cartilage or hard cheeses.
- Only use the knives on wooden or plastic cutting boards. Avoid cutting surfaces made of glass, stone or metal.
- Store the knife on a magnetic knife holder or in a knife sheath. Avoid loose drawers where the blade can be damaged.
- Sharpen the knife regularly with a wet whetstone or have it sharpened professionally.
- Avoid using knife sharpeners with steel or ceramic wheels as they can damage the hard steel.
- Keep the blade dry and clean – for longer storage, a thin layer of oil (e.g. camellia oil) can protect the steel from rust.
Japanese knives are made of thin, hard steel , which gives them extreme sharpness. However, this hardness makes them more vulnerable to chipping (small nicks in the edge) if used incorrectly. This is not a defect – but a characteristic of the fine material.

Real Products, Honest Pictures
At our core, we are all about the craft and the product itself. To give you the most authentic impression possible, we have chosen to take our own product photos.
Every image you see of our wood products is of a real item we have crafted for a customer. To ensure the best possible presentation, we may digitally adjust sharpness and colours or place the product in a relevant setting using artificial intelligence to better show it in a natural context.
A Guide to Variants
We are constantly expanding our product gallery. As many of our products come in a multitude of sizes and variations, we do not yet have photos of every single one. The image displayed when you make your selection primarily illustrates the chosen type of wood – not necessarily the specific size or design variation.
Every Piece of Wood is Unique
Wood is a living, natural material, and our passion is to create unique products with character. The grain and play of colours will therefore naturally vary from one product to the next. Please consider our photos as a source of inspiration and an indication of the high quality we deliver.
Any questions? We're happy to help.
Do you have questions about a design, size, type of wood, or do you have special requests? Please don't hesitate to contact us at info@rune-jakobsen.dk, and we will guide you to the right choice before you order.
