Shun Limited Edition knives are covered under our warranty. However, be aware that we may not be able to replace your knife with a new one due to lack of availability. In that case, once a knife has been evaluated by our warranty professionals and found to have a manufacturing defect, we will issue a voucher allowing you to choose Shun products listed on our website, of equal or lesser value to the voucher, as long as we have the product/s in stock.
Shun Cutlery products are intended and sold for legitimate culinary purposes only. The purchase, use, and ownership of knives are subject to a wide variety of local laws and regulations. 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. Any use of these products other than cutting is considered misuse and abuse and Kai USA Ltd. is not responsible for any injuries or damages caused by misuse and/or abuse.
Warning! Knives are extremely sharp tools and should only be used or handled with the utmost care and caution. Any use other than cutting is considered misuse and abuse—and will void your warranty.
Shun Cutlery/Kai USA Ltd. is not responsible for any injuries resulting from misuse or abuse of the product. Knives are intended to be used for cutting purposes only. Do not use knives for stabbing or piercing.
Use your knives on meats and vegetables only, not on bones or very thick-skinned vegetables. For this heavier kitchen work, try the Shun Classic Meat Cleaver (DM0767), or Shun Classic 8” Western Chef’s Knife (DM0766), which are designed to handle more aggressive work in the kitchen, such as breaking down chicken and preparing thick-skinned vegetables like butternut squash or melons.
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.

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 Warranty/Service Form (and keep a copy for yourself). Then close and tape your box according to shipper recommendations.
Looking for our sharpening services?
Your Shun knives come with free lifetime sharpening. For all the information, as well as the Sharpening Request Form you'll need, please visit our Sharpening page here.
About our Sharpening Services:
- Sharpen double-bevel knives at 16 degrees
- Sharpen single-bevel knives
- Repair microchips, small chips, and tips
- Hone serrated blades and shears
- Remove light rust (if you request it)
- Sharpen/repair serrated knives
- Sharpen/repair scissors
- Repair handles
- Re-apply logo
- Thin blade stock (work the flats)
- Replace missing rivets or end caps
- Repair large chips or cracks in blade
- Custom or specialty sharpening (such as uraoshi)
- Repair honing rods
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: 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 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.
For warranty evaluation or service, please fill out this online form
You may send multiple products with this single form; click “Add a Product” for additional space. Be sure to include the model number of your product. To find the model number, look on the back side of the blade. It is a combination of letters and numbers. The drop-down in the model number field will offer you options. Choose the one that matches your knife. If you don’t see your model number, or don't know the number, type "MISCSHUN" in that field and then choose "MISCSHUN" from the dropdown. You can write your model number in the Reason for Service area below.
Include a copy of the form with the items you are sending for warranty service. Be sure to include the return shipping & processing fee ($15 for US, $25 for Canada and Mexico) when you send in your knife/knives for service. Keep another copy of the form for your records. If you are unable to print the form, send the knives with a note that includes your Order number, name, address, and phone number. Knives received without an order number may be returned without service.
The model number is found on the back side of the blade, near where the blade meets the handle.
