Whetstone, Senjen, Double-Sided, Grit 400/1000

Whetstone SENJEN 400/1000 – restore your knife's sharp edge

This double-sided whetstone from Senjen allows you to maintain your knives with both coarse and medium sharpening. With grit sizes of 400 on one side and 1000 on the other, you can first remove material and then refine the edge. The stone weighs 770 grams, providing good stability during sharpening.

Ideal for kitchens where knives are used intensively and regular maintenance is necessary to maintain optimal sharpness.

Two sharpening grades in a single stone

This whetstone combines two important steps in the sharpening process. The coarser 400-grit side is well suited to restoring damaged edges and removing nicks in the blade. Once the basic edge shape has been established, you can switch to the 1000-grit side to refine the edge and give the knife a sharper finish. This combination makes the stone particularly valuable, as there is no need to invest in separate stones for the different sharpening stages.

Correct use delivers better results

For best results, the stone should be soaked in water for at least 30 minutes before use. Maintain a consistent sharpening angle of 12–13 degrees for most kitchen knives and work with even pressure along the stone. Always start with the coarser side (400) to shape the edge, then finish with the finer side (1000) to refine the sharpening. This method ensures a uniform and durable edge that delivers precise cuts and extends the lifespan of the knife.
