Whetstone flattening stone, Senjen, Grit 120 (medium)

Whetstone flattening stone – restores an even grinding surface

This whetstone flattening stone from SENJEN with grit 120 is an indispensable tool when your whetstones gradually lose their evenness and effectiveness. The flattening stone restores the flat surface of the stone while simultaneously removing metal particles that have become embedded in the surface during sharpening. With this tool, you can significantly extend the life of your whetstones.

Ideal for maintaining all types of water whetstones, ensuring you always have optimal conditions when sharpening your knives.

Renewing worn whetstones

Whetstones become uneven over time, particularly in the centre where they are used most. This makes it difficult to achieve precise sharpening of your knives. The SENJEN flattening stone with grit 120 works effectively to restore a completely flat surface. By removing hollows and unevenness, you ensure that the entire knife blade makes contact with the stone during sharpening, resulting in a more consistent finish.

Removes metal residue and improves sharpening efficiency

Over time, whetstones absorb metal particles from knives, which reduces their abrasive properties. This flattening stone removes these metal residues whilst simultaneously exposing fresh abrasive particles on the stone's surface. The result is a whetstone that performs almost like new, with a markedly improved cutting performance. You will notice the difference immediately – knives become sharper in less time and with less effort.

How to use the flattening stone

The flattening process is straightforward and takes only a few minutes. Begin by drawing a grid with a pencil on the surface of the stone. Then move the flattening stone in circular motions across the stone. Any areas where the pencil marks remain visible indicate hollows. Continue until all pencil marks have disappeared. Finish by bevelling the edges of the stone to prevent damage to knife blades during future sharpening.

With this whetstone flattening stone you get:
• The ability to restore a perfectly flat sharpening surface
• Removal of metal residues that impair the stone's sharpening ability
• Extended durability for your valuable whetstones
