Made-to-order Japanese knives

Global Delivery from Sakai

Across the world, discerning cooks seek authentic Japanese knives from Sakai — Japan’s legendary knife-making city with over 600 years of tradition.
At KIREAJI, we work alongside master artisans in Sakai to fulfill that desire, shipping genuine handcrafted knives directly from the workshop to kitchens worldwide.

Global Delivery from Sakai
  • 1. Honbazuke (Initial Sharpening)

    If you wish to request Honbazuke, please select “Yes” when ordering. This service is provided free of charge.

    Honbazuke is a practical initial sharpening performed for first use. As the knives are shipped internationally, the blade must be protected during transit. You may make final adjustments yourself to suit your personal preferences.

  • 2. Protective Coating on New Japanese Knives

    New Japanese knives are coated with a transparent protective liquid vinyl coating to prevent rust during storage and international shipping.

    Especially on mirror-polished blades, this coating may appear as a rainbow-like film depending on the lighting. This is not a defect in the steel or the finish.

    How to remove the coating:

    ・Wash the blade gently with a sponge and mild dish soap, then rinse with lukewarm water.
    ・If difficult to remove, gently wipe while washing using tissue paper or a soft cloth.
    ・If residue remains, wiping with a cloth lightly moistened with alcohol (sanitizing ethanol) is effective.
    ・Never use metal scrubbers or abrasive cleaners, as they may damage the blade surface.

  • 3. Handcrafted Nature

    Each knife is handcrafted by skilled artisans and is therefore unique.

    Minor scratches or marks may be visible as a result of the handmade production process. These do not affect performance or functionality. We kindly ask for your understanding in advance.

  • 4. Natural Materials

    As buffalo horn is a natural material, color variations may occur. The actual product may differ slightly from the photos shown.

  • 5. Measurements

    Please consider the listed weight and length as approximate values.

  • 6. Inventory

    We carefully manage our stock. However, in the rare event that an item becomes unavailable after ordering, we will notify you by email.

If you have any questions, please feel free to contact us.  (Estimated reply time: within 10 hours)

    In this video, discover why professional chefs place such importance on high-quality knives, and how the right knife can deepen both precision and enjoyment in everyday cooking.
