Precautions
-
- 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 preferences. - Each piece is handmade and therefore unique. Please consider the weight and length as approximate.
- As buffalo horn is a natural material, color variations may occur, and the actual product may differ slightly from the photo.
- We carefully manage our inventory, but in the rare case an item is out of stock, we will notify you by email.
- If you wish to request Honbazuke, please select "Yes" when ordering. (Free of charge)
If you have any questions, please feel free to contact us. (Estimated reply time: within 10 hours)
