Precautions
-
1. Honbazuke (Initial Sharpening)
If you wish to request Honbazuke, please select “Yes” when ordering. (Free of charge)
At KIREAJI, we provide the Honbazuke service free of charge upon request.
Please note that this is a practical initial sharpening.
As the knives are shipped internationally, the blade must be protected during transit.
You can make the final adjustments yourself to suit your personal preferences.
2. Handcrafted Nature
Each piece is handcrafted by skilled artisans and therefore unique.
Minor scratches or marks may be visible due to the handmade production process; however, these do not affect performance or functionality.
We kindly ask for your understanding in advance.
3. Natural Materials
As buffalo horn is a natural material, color variations may occur, and the actual product may differ slightly from the photo.
4. Measurements
Please consider the listed weight and length as approximate values.
5. Inventory
We carefully manage our stock, but in the rare case an item is out of stock, we will notify you by email.
If you have any questions, please feel free to contact us. (Estimated reply time: within 10 hours)
