Whetstone, Tyrolit, Double-sided, Grit 150/400

Double-sided whetstone for precise knife sharpening at home

This double-sided whetstone from Tyrolit allows you to maintain the sharpness of your knives with professional precision. With grit sizes of 400 and 150 on each side, you get both a coarse and an extra-coarse sharpening surface in a single stone, making it ideal for restoring dull knives. The stone is made from durable silicon carbide and measures 20x5x2.5 cm.

Ideal for kitchens where knives regularly need their edge refreshed, and where you want full control over the sharpening process yourself.

Two sharpening grades in one stone

The double-sided design gives you two different grit sizes in a single product. The coarse side with grit 150 is well suited for straightening very dull knives or those with chips in the edge. The less coarse side with grit 400 is used to refine the cutting surface and give the knife a more precise edge. This combination makes the stone extremely versatile across different stages of the sharpening process, without the need to invest in multiple separate whetstones.

How to get the best results

For best results, soak the stone in water for at least 30 minutes before use. Maintain a consistent sharpening angle of 12–13 degrees for most kitchen knives, and move the blade in a smooth, even stroke along the stone. Start with the coarse side (150) to remove larger imperfections, then finish with the finer side (400) to refine the edge. The green colour makes it easy to identify the different sides of the stone, so you always know which grit you are working with.

Technical specifications

The stone is made from hard-wearing silicon carbide, known for its hardness and ability to hold its shape even after many hours of use. Weighing 471 grams, it sits stable on the work surface during sharpening, and the 20x5x2.5 cm dimensions provide ample room to work with both small and large knives. The green colour helps you identify the different sides of the stone.
