General Information
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 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.

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.

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.
