Limited Lifetime Warranty

Kershaw Knives from Kai USA Ltd. carry a limited warranty for the lifetime of the original owner, except when stated otherwise. We guarantee our knives against manufacturing defects in material and construction and to perform as advertised when properly used and maintained. The Limited Lifetime Warranty is non-transferable and does not extend to normal signs of wear, rust, damage or breakage due to improper use, improper maintenance, accidents, loss or theft. Any product we determine to be defective will be repaired or replaced solely at our discretion. To receive warranty repair or replacement, the owner must send the product to be evaluated by Kai USA Warranty Services in our Tualatin, Oregon headquarters. In addition to the provisions of this warranty, the owner may also have other rights that can vary by state. The Limited Lifetime Warranty does not apply to the TX Tool. No other warranties are implied or expressed other than what is specifically stated here.

Shipping Internationally

When shipping from anywhere outside the United States, you must include our Warranty Service Form (inside the package) AND the appropriate Customs Declaration Form required by US Customs and Border Protection (on the outside of the package). Your carrier will help you decide on the correct form to use. For Canada Post, for example, you will need form CN22 or CN23.

To avoid unnecessary duty charges, under "Quantity and detailed description of contents" on the form, write the number of knives you are sending and note the description as warranty service.

Mislabeled or misdeclared shipments can cause extended delays through customs.  We encourage all international customers to contact us via email prior to sending any items in for service. We can help make sure you have correct codes and values to make shipping as speedy as possible.

We reserve the right to refuse any package or to charge you—the sender—for any duties incurred by us for wrongly declared or undeclared packages shipped to our Warranty Department.
