Maintenance tips

Have it sharpened on a water stone by a professional every year. Store in a dry place. Wash immediately after use and dry completely before storing. Do not let soak. Not dishwasher safe.

Product notes

Please note that each handle is unique and may have distinct variations, such as differences in shades or colors in the buffalo horn, which is part of its authentic and handcrafted character.

Guarantee

Every knife carries a lifetime warranty against obvious manufacturing issues. For example, if the handle peels or cracks after a few weeks of proper use. Or if the blade develops a crack from the edge to the spine. These issues are rare, but can occur. In such cases, you will be offered an exchange for the same product or a refund. Since each case is different, it is at our discretion to assess whether our lifetime warranty against obvious manufacturing issues applies.

After-sales service
