I've always been fascinated with traditional Japanese swords and sword-makers, so I naturally gravitated towards Kamikoto products which are steeped in the same traditions. These are the most amazingly sharp knives I've ever seen, and I have no doubt they are capable of splitting atoms! I now own two complete sets of knives (the entire line), plus many extra knives that I give away to friends and family, who are equally amazed at the quality, sharpness, and presentation... the little wooden boxes are a great touch. Plus their customer service is second to none; I've done lots of online shopping, and no company I've ever dealt with can even come close to the professionalism, courteousness, and generosity that Kamikoto exhibits on a regular basis. So whether you're a weekend warrior in the kitchen like myself, or a professional chef in a 5-Star restaurant, you can always depend on Kamikoto knives... there's nothing sharper.
