Sharpening and Care

To sharpen a KAI knife in the traditional Japanese and therefore professional way, 
we recommend using ceramic-bonded whetstones. 


Moreover, KAI also offer electronic grinders, as well as care accessories 
and blade protectors. A detailed manual for re-working symmetric and asymmetric blades with traditional Japanese whetstones can be found here.

KAI Japan has been driven by a constant drive for aesthetic design, technical innovation & outstanding quality, enjoying cult status in Japan. These amazing razor-sharp knives are created in Seki City, Japan’s 700-year-old center for Samurai swords. 

Founded in Japan in 1908, KAI has crafted super sharp and functional knives for over a century. Built to stay strong and maintain their edge, you'll love the control and slicing precision these blades provide. Knives are not their only speciality — KAI's prep tool, knife sharpener and knife accessory ranges are perfect additions to any home cook's kitchen collection.
