Kai 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 Kai products listed on our website, of equal or lesser value to the voucher, as long as we have the product/s in stock.
Kai 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 will void your warranty. Kai Housewares/Kai USA Ltd. is not responsible for any injuries resulting from misuse or abuse of the product.
Warning! Knives are extremely sharp tools and should only be used with the utmost care and caution. Knives are intended to be used for cutting purposes only. Do not cut frozen food with these knives. Do not use knives for stabbing or piercing. Use your knives on produce, proteins such as meat and fish, but not on bones or very thick-skinned produce. For this heavier kitchen work, try the Kai PRO Meat Cleaver (HT7067), which is designed to handle more aggressive work in the kitchen, such as breaking down proteins and preparing thick-skinned produce like butternut squash or melons.
Please be sure to read the Limited Lifetime Warranty information above.
In addition, there may be cases when a Kai 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.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 Kai product directly from us.
If you wish 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 it is not reclaimed 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 Kai 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)
- 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 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.
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 "MISCHW" in that field and choose "MISCHW" 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.
The model number is found on the back side of the blade, near where the blade meets the handle.
