About this artisan

KISEKI Petty Knife - Japanese Food Craftsman Shop

Fukuda Hamono

For centuries, Japanese blades have balanced artistry and performance. Yet, traditional steel knives came with trade-offs, carbon steel rusts, stainless steel dulls.

Seeking a better way, engineer Keisuke Fukuda, set out to combine the best of both worlds, pioneering the use of ultra-hard cemented carbide in a kitchen knife.

The result was the KISEKI collection of knives made by his family company Fukuda Hamono, a workshop with more than 126 years of history. The KISEKI knives have an edge made from tungsten carbide that glides effortlessly, holding its sharpness longer than conventional blades.

But creating KISEKI required pushing beyond the limits of conventional knife-making.

The dense, weighty carbide cannot be pressed or laser-cut like steel. Each blade is wire-cut over ten hours with 1/1000 mm precision, then finely ground using diamond wheels to achieve a razor-thin edge that preserves the cellular structure of food.

Every knife is made to deliver the same flawless quality, every single time.

Do I need to purchase a separate KISEKI Knife Attachment for Sharpening in addition to my KISEKI Diamond Whetstone?

No. You do not need to purchase another KISEKI Knife Attachment for Sharpening separately. One attachment suitable for the knife size (Santoku or Petty) you purchased is included with your KISEKI Diamond Whetstone.

If you wish to use your KISEKI Diamond Whetstone with both your KISEKI Santoku and Petty knives, you may wish to purchase another attachment separately for the size knife you did not originally purchase a Diamond Whetstone for.

Can I use my diamond whetstone to sharpen other knives?

We do not recommend using your KISEKI diamond whetstone for other knives made from different materials. The KISEKI diamond whetstone was designed for use specifically with KISEKI Santoku and Petty knives by Fukuda Hamono.

How do I use my diamond whetstone to sharpen my KISEKI knife?

Here is a short video on how to use the sharpening attachment with your dedicated KISEKI Diamond Whetstone to brush up your KISEKI knife as intended by Fukuda Hamono. Please be sure to use it on a stable, non-slip surface, ensuring that it is right side up (the side with diagonal patterned lines facing up) and wet with water before use.
