Free Sharpening Service
We will sharpen your Shun cutlery for free, for as long as you own it. It’s as simple as that. You pay for shipping and processing, and our expert sharpening services are FREE. If you live in the area, you may also bring your Shun knives in for free sharpening. We can sharpen up to two knives while you wait; more than two and they will be ready for you to pick up the next day. Please be aware that sharpening actually removes metal from the blade. This is normal and is to be expected. Note that serrated knives can be honed by our service, but cannot be sharpened.
Free sharpening services apply to purchases made through authorized dealers only. Click here for more information on authorized dealers.
Kai USA can only accept sharpening requests for products purchased in the USA, Canada, or Mexico. Please see more information under "Information for Customers Outside USA/Canada/Mexico" in the ABOUT OUR SHARPENING SERVICES accordions.
If you have questions about our sharpening services or your warranty and how to take advantage of it, please check our FAQs to see whether your question has already been answered. If not, just contact our Warranty Service Team and they’ll be happy to help.
Shipping & Processing Fees
Shipping and processing fees are required for all Kai sharpening and warranty services ($15 for US, $25 for Mexico & Canada). If you are outside North America, please contact us for a quote. Please enclose check or money order with your items (payable to Kai USA LTD) or include credit card information in the space provided on the Sharpening Request Form.
IMPORTANT: Sharpening service requests that do not include the shipping and processing fee will not be able to be processed and may be returned without service.

Like those of most manufacturers, Shun single-beveled blades have a micro-bevel on the blade back. This enables you to use the blade right out of the box-and to be able to touch up the edge using a smooth hone or 6000-grit whetstone. When you send your single-bevel Shun in for sharpening, we will sharpen it in this original factory manner.
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 your shears have grown dull or the edges are damaged, we recommend looking for an experienced shear sharpener in your area.
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.
We’re sorry, but we only provide warranty and sharpening service to customers who purchased their products in the USA, Canada, or Mexico through Kai USA or any of our authorized dealers. If you purchased your products elsewhere, please contact the authorized dealer from whom you originally purchased. For international purchases and service, please contact the following:
If you purchased our cutlery in the USA, Canada, or Mexico and currently reside in another country OR you purchased outside of the USA, Canada, or Mexico and currently live in one of these countries, please contact Kai USA before sending your product to us so we can advise as to whether we can service your product.
To send in a Shun product for evaluation and/or warranty service, including repair and sharpening, please read all the information on this page.
Then, fill out the Sharpening Request 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 Shipping and Processing Fees. 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.
Please allow up to six weeks for processing, including delivery time.
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. Don't let that happen to your package. Instead, 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 Sharpening Request Form and keep a copy for yourself. Then close and tape your box according to shipper recommendations.
SHIPPING FROM CANADA/MEXICO
Kai USA can only accept sharpening requests for products purchased in the USA, Canada, or Mexico. When shipping from Canada or Mexico, you must include our Sharpening 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.
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 make receiving warranty service for your Shun products simpler, please return them to the authorized retailer from whom you originally purchased them. Do not send them back to Kai USA. Only an authorized retailer will be able to support your warranty service. 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.
Additional information for Canadian/Mexican customers can be found under "Information for Customers Outside of USA/Canada/Mexico" above.
