My understanding is specifically that the instructions are incorrect in stating that it can and should be used on anything but ceramic knives.
Ok... I did look at the scan. The information on the box is useless. You aready have more information. The information I gave you the first time is more accurate than any of the other information. This IS the correct information on that product. What is on the box IS NOT.
Our Ceramic Knife Diamond Sharpener for Ceramic Knives - #94035 is the most popular ceramic knife sharpener in Japan. In fact the Japanese company, Dia Kirex, would not let MIU change the packaging for import into the USA, because they wanted to maintain their identity. Although ceramic knives last 10 times longer then steel, they eventually need to be sharpened and this great knife sharpener makes it easy. Simply swipe your ceramic knife, back and forth a few times, through the diamond sharpening mechanism. Its unique design angles your knife and sharpens both sides at once. The sharpener and non slip feet to hold it in place on your counter or tabletop and a easy to grip handle to make your sharpening easy and trouble-free. Works with all ceramic knives. NOTE: Use only a diamond sharpening mechanism on your ceramic knives - use of sharpeners, for steel knives, will only dull your ceramic blades. -- For over 15 years MIU has been producing kitchenware for the gourmet industry. Their extensive knowledge on product design, market demand and most importantly what customers want has made their products favorites all over the world. Their products are elegant and made from the finest quality materials including 18/10 stainless, ceramic, glass & natural woods. -- Size: 7L x 2H x 1.5D Inches; Color: Black

At any rate, please be careful using this on your ceramic knives. Akthought it is "designed" for them, from what I've read so far, it's a piece of junk and shouldn't be trusted with expensive knives of any kind. You'd be best off getting a product that everyone that has used doesn't hate. At appears as though the device does not do what it's supposed to... and that's almost unanimous among the customer comments I have seen. That's what I've gathered anyway.
