I ordered Kuro set for a gift and received somewhat flawed one. Their customer service immediately answered to my email and asked some pictures of the item. After examining the pictures, they immediately replaced the flawed one. I really appreciate their quick action. However, Kuro set was not extremely sharp as much as I expected compared to their other single beveled knives although they advertised as best knife ever amongst their products. Overall, I was satisfied their customer service but have a question mark on the Kuro set.
