WARRANTY & SERVICE INFORMATION
Thank you for choosing Kershaw. From this page, you can request warranty evaluation, repair and sharpening service, and free replacement parts.
To ensure you get a lifetime of service from your Kershaw, our products are backed by a Limited Lifetime Warranty against manufacturing defects. In addition to supporting our products with this warranty, we will be happy to repair and sharpen your Kershaw knife for free when you send it in for warranty service.
If you have questions about your warranty or how to take advantage of it, check our FAQs to see whether your question has already been answered. If not, just email our warranty team for more information.
Kai USA can only accept warranty/parts requests for products purchased in the USA, Canada, or Mexico. If you purchased your product outside of the USA, Canada, or Mexico, please contact the authorized dealer from whom you originally purchased them to receive warranty service or parts.
Pocketclips can bend. Screws can get lost. To keep your Kershaw on the job, we are happy to provide a selection of free replacement parts. Please click on "Available Kershaw Replacement Parts" on the right of this page for a complete list. Parts can be sent only to the USA, Canada, and Mexico. If you are outside of those countries, contact the authorized dealer where you originally purchased your knife.
In addition to the replacement parts above, we can also replace a broken blade that is not covered by warranty for $25 (effective 11/1/21). Please see the FAQs under Warranty Questions for details. To have a blade replaced, just add the $25 fee to your payment when you send in your knife and make a note in the “Reason for Service” box on the form. Not all blades are available at all times. Please note that replacement blades will not have the original laser markings. If there is any issue with your request, the warranty team will contact you.
As a courtesy, we sharpen every knife that is sent to us for service. Unfortunately, we are unable to sharpen serrations but we can still sharpen the plain edge portion of your blade. Additionally, we know that some of you put a special edge on your knives. So, if you do NOT want us to sharpen your knife, just make a note in the “Reason for Service” box on the form.
AUTOMATIC KNIVES, BUTTERFLY KNIVES AND MORE INFORMATION
If you need service for an automatic or butterfly knife, be sure to read the additional information and include the required release form with your knife, in addition to a warranty request form. For additional information, click the arrows on the boxes to read our warranty, learn about replacement vouchers, counterfeits, and more.
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, Fire Starter, or Kershaw Oil. 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.
Kershaw knives are intended and sold for legitimate everyday carry, sporting, and/or culinary purposes only. The purchase, use, and ownership of knives are subject to a wide variety of federal, state, and local laws and regulations. Always comply with all laws and regulations in effect in your area. Due to the complexity and constantly changing nature of these laws and regulations, it is the responsibility of the buyer to investigate and comply with the laws and regulations that apply in his or her specific area. You, and not Kai USA Ltd., are solely responsible for any claims resulting from violation of these laws and/or regulations.
Knives are extremely sharp tools and should only be used or handled with the utmost care and caution. Any use other than cutting (such as prying or twisting) is considered misuse and abuse—and will void your warranty. Kershaw Knives/Kai USA Ltd. is not responsible for any injuries resulting from misuse or abuse of the product.
Do not use any Kershaw knife (other than the Ion 1747BW or Aethon 1748 throwing knives) as a throwing knife or a stabbing device. Throwing knives and knives developed for stabbing have a distinctly different design and function. Kershaw knives are not intended for throwing or stabbing; they are designed for cutting purposes only.
Due to state and federal regulations, automatic & butterfly knives sent for service require a completed Automatic & Butterfly Knives Release Form.
If you have any questions, please contact us at 1-800-325-2891 or by email.
There may be cases when your knife has been evaluated and is eligible for warranty service but is not able to be repaired or replaced. This can be true with discontinued models of which we no longer have stock. In such cases, at our discretion, we will offer a voucher for a replacement knife of equal or lesser value, as defined by the Manufacturer’s Suggested Retail Price (MSRP). The voucher can only be used through the Kai USA Warranty Department and some exclusions apply. If you prefer to have your original knife returned instead of using the voucher, 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 you do not call us to let us know 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: Shun Multi-Purpose Shears (model DM7300), Shun Herb Shears (model DM7100), Shun Kitchen Shears (model DM7240), Kai Multi-Purpose Shears (model KA7300), Kai Kitchen Shears (model KA7500), Kershaw Taskmaster Shears (model 1120), and Kershaw Taskmaster Shears 2 (model 1121). 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 Service Team toll-free at 1-800-325-2891.
To keep your Kershaw on the job, we are happy to provide these free replacement parts:
- Button spring
- Coil spring
- Grip inlays
- Handle screw set
- KVT bearing washers (for KVT manual opening knives)
- Lock button
- Pivot bolt set
- Pivot washers
- Pocketclip set
- Safety Tip-lock set (for Leek, Scallion, Chive)
- Spacer set
- Stop pin
- Torsion bar (for assisted opening knives)
Please note: We can only ship replacement parts to the USA, Canada, and Mexico. If you are not in one of those countries, please contact the dealer from whom you originally purchased your knife for information on receiving replacement parts.
To request parts, use the online Parts Request Form below. Please be advised that we do not stock all parts for all import models at all times and we may not have parts for discontinued models. In addition, parts for Factory Special Series, Limited Edition, and Dealer Exclusive knives are very limited and might not be available for your knife. If there is any issue with your parts request, our warranty team will contact you.
Please see the "International Customers" section for information on international warranty.
We are happy to provide warranty support to our international customers through our authorized dealer/distribution network. In order to receive warranty support, your knife must have been purchased from one of our authorized dealers. Unauthorized dealers may or may not be willing to honor our warranty policy and because they do not purchase direct, we have no authority to require that they do so. We are unable to honor warranty claims for knives purchased from unauthorized international dealers. A list of our authorized international dealers can be found here. We ask that you work with your dealer for any repairs or part requests, and again, we only recommend that you purchase from our authorized dealers!
Please note: We can only ship replacement parts direct to customers in the USA, Canada, and Mexico. If you are not in one of those countries, again we ask that you please contact the dealer from whom you originally purchased your knife for information on receiving replacement parts. Please see the Available Kershaw Replacement Parts section for more information on replacement parts.
Request Warranty/Service or Parts
If you think your product may have a problem in its original material or craftsmanship, please send it in for evaluation. Review the shipping information and complete the Warranty/Service Form below.
Please include a $7 Return Shipping & Processing Fee when you send your knife in for service. This is a flat fee, no matter how many knives you send. Just add your credit card information to the Warranty/Service Form or include a check or money order in the shipping box along with your knife and the completed form.
To request parts, please use the Parts Request Form.
To send in a Kershaw product for evaluation and/or warranty service, including repair and sharpening, please read all the information on this page. Kai USA can only accept warranty requests for products purchased in the USA, Canada, or Mexico. If you are outside of the USA, Canada, or Mexico, please return products to the authorized dealer from whom you originally purchased them.
Then, fill out the Warranty/Service Form below. You can list multiple products on this same form. Print two copies of the form from this webpage or from the follow-up email you will receive. On one copy, add your credit card information or include a check or money order for the $7 Shipping and Processing Fee. Place the completed form, along with your check or money order, if using, in the shipping box with your knife. Save a copy of the form for your records.
Package the items safely. Please use a box; envelopes are not recommended.
Ship via a carrier with a tracking service. There must be a way to track your package through your carrier. Kai USA Ltd. cannot be responsible for your item/s unless we have confirmation that your package was delivered to us.
IMPORTANT: We are not responsible for damage to or loss of items that are not properly packaged and shipped.
Even dull knives can be dangerous—especially if not packed properly for shipping. We’ve received packages with blade tips that have pierced the cardboard box and boxes with great jumbles of knives just rattling around inside, cutting into each other. Please follow these easy tips for safe packing:
Do not place loose knives in shipping box.
Carefully wrap and package knives in box.
Tip #1: Sheath or wrap fixed-blade knives and kitchen knives. If the knife has a sheath, place it in its sheath. If not, wrap it in several layers of newspaper or bubble wrap, making sure to fully cover the tip. If you are returning more than one knife, wrap each knife individually, and then wrap them all together so that they won't roll around in the box, possibly causing damage to the blades or handles.
Tip #2: Make sure folding knives are closed, then wrap the closed knife in several layers of newspaper or bubble wrap. If you wish to keep your original box, please do not send it in with your warranty shipment. All boxes sent in with warranty shipments will be recycled.
Tip #3: Fill your box with packing material—such as packing peanuts, bubble wrap, or newspaper. Place a layer of packing material in the bottom of your shipping box. Then place the knives on top of the filler and, finally, add another layer of filler on top of the knives.
Tip #4: Include a copy of your completed Warranty/Service Form and keep a copy for yourself. Then close and tape your box according to shipper recommendations.
Information for Canada and Mexico Customers
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 forms.
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 mis-declared shipments can cause extended delays through customs. If you have any questions, contact our warranty team and they’ll be happy to help.
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.
Information for Non-USA/Canada/Mexico Customers
To receive warranty service or parts, please contact the authorized dealer from whom you originally purchased your Kershaw knife rather than Kai USA. To ensure that you’re purchasing from an authorized retailer, please check our list of authorized distributors and dealers here. If a distributor is listed for your area, contact them to make sure the retailer you would like to purchase from is fully authorized. Thank you for supporting our authorized retailers.
