You have several options:
Return them to us for FREE sharpening
Kai cutlery owners may return their Kai knives to our Tualatin, Oregon facility for free sharpening. To take advantage of this service, please see our Warranty service information. Ship your knives to us using the carrier of your choice, however we strongly recommend a carrier that provides a tracking number. Without a tracking number, you will have no way of knowing that your package has arrived at our facility—and neither will we. We cannot be responsible for shipments without a tracking number.
Sharpen them yourself with a pull-through sharpener
For an electric sharpening option we recommend our Electric Sharpener. For a manual pull-through, try our Diamond and Ceramic Retractable Sharpener, both of which match the 16° angle of our cutlery. But please remember that sharpening is not something that should be done on a weekly basis. Sharpening actually removes some of the metal from the blade, so sharpening too frequently may reduce the life of your knife.
