Thank you so much for your purchase and for joining the Kessaku family! As a member of our family, you’re entitled to our worry-free lifetime warranty. Simply visit our Product Registration Page. Rest assured that we’ve got you covered.

You can use our Contact Us form, or email us at Help@KessakuUSA.com with any issue or concern so that we can immediately do our absolute best to make it right!

Please note that this warranty applies to manufacturing defects (which we’re very proud to define as “rare”) and, of course, does not include regular routine maintenance, like sharpening and honing, general wear and tear, or issues incurred through improper or unintended use.
