    • 2000/6000 grit ceramic whetstone
    • Anti-slip rubber and natural bamboo base for safety and comfort

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 2000/6000 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 2000/6000 double-sided whetstone offers you 2 grits to sharpen your knife with a single stone: a coarse 2000-grit side to reshape a dull blade and rougher edges, and a finer 6000-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.


Comfortable and well-balanced. I love the hand-hammered pattern on the blade. Excellent craftsmanship.

This knife is made of 440C steel from Japan. 440C is a high-carbon stainless steel, meaning that it combines the property of high-carbon steel (very hard due to the high carbon content of 0.95%+ and the vacuum heat treatment, therefore very sharp and able to keep its edge for much longer than other steels) and stainless steel (ability to resist corrosion and stains). So the blade will not rust, but you have to care for it properly by washing it with soapy water and drying it quickly after using it.

Do not put it in the dishwasher or leave it to soak in the sink.

A “cheap” knife will end up costing you more in the long run, because it can break or turn dull. Low quality steel will not keep a sharp edge no matter how many hours you waste on sharpening, and you will end up having to buy a new knife every year or so.

There are plenty of “cheap” knives that cannot perform to decent standards and very few options for chefs who are passionate about cooking, need the right tools to assist them in their career or hobby but are not willing to overspend on a brand name. Get your KOTAI knife today for a lifetime of safe and delicious cooking.
