CHARACTERISTICS

  • Sharp Ever After

    Get the most out of your knives.
    With the 2 different grits, you can conveniently keep your knives razor-sharp yourself.

  • Safety First

    The KOTAI 180/800 Combination Whetstone is mounted on a rubber base for stability.
    Not only does this make it safer for your fingers, it will also allow you to keep the sharpening angle constant.

  • Prolong The Life of Your Knives

    If your knife’s blade edge gets dented or too dull for the regular honing steel, the whetstone will help restore its original razor-sharp edge with minimal waste of steel.
    Soak the whetstone for 15 minutes before use (until air bubbles stop coming out of the stone).

The KOTAI 180/800 double-sided whetstone offers you 2 grits to sharpen your knife with a single stone: a coarse 180-grit side to reshape a dull blade and rougher edges, and a finer 800-grit side to maintain or give a razor-sharp edge finish.

Our 4-piece sharpening set contains everything you will require to keep your blades razor-sharp at all times.

Your Questions, Answered

How do I choose my sharpening stone?

The smaller the number, the more abrasive the grit. A low number is useful for restoring a very dull blade or for occasional sharpening. On the other hand, a less abrasive grit is recommended for achieving a very sharp edge, but it will be less effective for sharpening blades that are poorly maintained.

→ Sharpening and honing.

How often should I use my sharpening stone?

It depends on how often you use your knives.

For home cooks, regular use of a honing rod should be complemented by one or two sharpening sessions per year.

For professional chefs who spend long hours in the kitchen, a sharpening session every 1 to 2 months is recommended.

How do I use my sharpening stone?

Soak your stone in water for 10 minutes and make sure it stays wet throughout the sharpening session.

Use the 15° angle guide and run the blade over the stone while applying pressure with your fingers: don’t forget the base and the tip of the edge.

Repeat on both sides of the blade until you achieve a satisfactory result.

Finally, rinse all your equipment and let your sharpening stone dry for 48 hours before storing it.
