If you have questions about your warranty or how to take advantage of it, please check our FAQs to see whether your question has already been answered.

Special Information About Automatic Knives
Due to state and federal regulations, automatic knives must be returned for warranty service via an authorized dealer or military/law enforcement procurement office. Once the knife has been serviced, we will ship it back to the dealer or officer who originally sent it to us. You will receive the serviced knife from them. If you are a member of law enforcement or the military, you may directly ship your automatic knife to us for warranty service and we can return it directly to you. (Download the Automatic Knives Release Form at the link below for additional details.)
If you have any questions, please contact us at 1-800-325-2891 or by email. If you are an authorized dealer, military/law enforcement procurement officer, or a member of the military or law enforcement, you can download the required Automatic Knives Release Form here.
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. This warranty is void on products that have been modified in any way. 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. Kai USA Ltd. reserves the right to determine what constitutes normal wear, improper use/maintenance, and modification.
We reserve the right to make changes to this warranty at our discretion and without notice.
Please be sure to read the Limited Lifetime Warranty information above.
In addition, there may be cases when a Kershaw knife has been evaluated and is eligible for warranty service, but may not be able to be repaired or replaced. This can be true with discontinued models for which we may no longer have parts or stock. In such cases, at our discretion, we will issue a voucher for the original Manufacturer’s Suggested Retail Price. The voucher value can then be applied to the purchase of a current-model Kershaw—directly from us. If you also wish to have your original knife returned, please call our warranty team toll-free: 1-800-325-2891. We will retain the knife for 30 days from the date the voucher is issued. If it is not reclaimed by then, the knife will be recycled.
We’re sorry, but our warranty service center does not have the proper equipment to successfully sharpen scissors/shears. However, we would be happy to hone any of the shears Kai USA sells: Kershaw Taskmaster Shears (model 1120), Shun Multi-Function Shears (model DM7300), Shun Herb Shears (model DM7100), and Shun Premium Kitchen Shears (model DM7240). Honing simply brings the edge back to true; it does not remove metal from the shears.
If you have Kasho professional hair shears, please send them to Kasho for sharpening.
If you have Kai textile shears, please take them to a professional shears sharpener in your area.
Before you send scissors/shears in for service, please call our warranty team toll-free at 1-800-325-2891.
